Re: [ESS] Feature idea: insert expression before <- at point

[Michael Lawrence via ESS-help]

+1, good idea.

In some ways this is the edit-time equivalent of the pipe operator and its
back reference ".", which can place cognitive burden on the reader.

You give examples of replacement. Repetition also arises in extraction,
e.g., with [().

data[,"columnA"][_POINT_ > 10]

One concern is that this might discourage semantic labeling of expressions
through assignment (a problem shared with the pipe).

Re: [R] How to filter data using sets generated by flattening with dcast, when I can't store those sets in a data frame

[Michael Lawrence]

The data structures you mention are complex, and too much of their
complexity leaks into client code. Instead, aim to use higher level code
constructs on simpler data structures. In R, the most convenient operations
are those that are statistical in nature.

For example, one might solve your problem by saying: restrict to the subset
of the important days (1, 4, 7), and count the occurrences of each patient
in that subset to find those patients with the sufficient number of
important measurements.

criticalDays - c(1, 4, 8)
criticalDf - subset(df, Day %in% criticalDays)
keepPatients - table(criticalDf$ID) == length(criticalDays)
df[keepPatients[df$ID],]

Note that the code above assumes that the ID variable is a factor, which it
should be.

wrote:

 This is a fairly long question. It's about a problem that's easy to
 specify in terms of sets, but that I found hard to solve in R by using
 them, because of the strange design of R data structures. In explaining it,
 I'm going to touch on the reshape2 library, dcast, sets, and the
 non-orthogonality of R.

 My problem stems from some drug-trial data that I've been analysing for
 the Oxford Pain Research Unit. Here's an example. Imagine a data frame
 representing patients in a trial of pain-relief drugs. The trial lasts for
 ten days. Each patient's pain is measured once a day, and the values are
 recorded in a data frame, one row per patient per day. Like this:

   ID  Day  Pain
11  10
12   9
14   7
17   2
22   8
23   7
31  10
33   6
34   6
38   2

 Unfortunately, many patients have measurements missing. Thus, in the
 example above, patient 1 was only observed on days 1, 2, 4, and 7, rather
 than on the full ten days. But a patient's measurements are only useful to
 us if that patient has a certain minimum set of days, so I need to check
 for patients who lack those days. Let's assume that these days are numbers
 1, 4, and 9.

 Such a question is trivial to state in terms of sets. Let D(i) denote the
 set of days on which patient i was measured: then I want to find out which
 patients p, or how many patients p, have a D(p) that contains the set
 {1,4,9}.

 The obvious way to solve this is to write a function that tells me whether
 one set is a superset of another. Then flatten my data frame so that it
 looks like this:

   ID  Days
1  {1,2,4,7}
2  {2,3}
3  {1,3,4,8}

 And finally, filter it by some R translation of

   flattened[ includes( flattened$Days, {1,4,9} ), ]

 I started with the built-in functions that operate on sets represented as
 vectors. These are described in
  https://stat.ethz.ch/R-manual/R-devel/library/base/html/sets.html ,
 Set Operations. For example:

union( c(1,2,3), c(2,4,6) )
   [1] 1 2 3 4 6
intersect( c(1,2,3), c(2,4,6) )
   [1] 2

 So I first wrote a set-inclusion function:

   # True if vector a is a superset of vector b.
   #
   includes - function( a, b )
   {
 return( setequal( union( a, b ), a ) )
   }

 Here are some sample calls:

includes( c(1), c() )
   [1] TRUE
includes( c(1), c(1) )
   [1] TRUE
includes( c(1), c(1,2) )
   [1] FALSE
includes( c(2,1), c(1,2) )
   [1] TRUE
includes( c(2,1,3), c(1,2) )
   [1] TRUE
includes( c(2,1,3), c(4,1,2) )
   [1] FALSE

 I then made myself a variable holding my sample data frame:

   df - data.frame( ID = c( 1, 1, 1, 1, 2, 2, 3, 3, 3, 3 )
   , Day = c( 1, 2, 4, 7, 2, 3, 1, 3, 4, 8 )
   )

 And I tried flattening it, using dcast and an aggregator function as
 described in (amongst many other places) http://seananderson.ca/2013/
 10/19/reshape.html , An Introduction to reshape2 by Sean C. Anderson.

 The idea behind this is that (for my data) dcast will call the aggregator
 function once per patient ID, passing it all the Day values for the
 patient. The aggregator must combine them in some way, and dcast puts its
 results into a new column. For example, here's an aggregator that merely
 sums its arguments:

   aggregator_making_sum - function( ... )
   {
 return( sum( ... ) )
   }

 If I call it, I get this:

 dcast( df, ID~. , fun.aggregate=aggregator_making_sum )
   Using Day as value column: use value.var to override.
 ID  .
   1  1 14
   2  2  5
   3  3 16

 And here's an aggregator that converts the argument list to a string:

   aggregator_making_string - function( ... )
   {
 return( toString( ... ) )
   }

 Calling it gives this:

 dcast( df, ID~. , fun.aggregate=aggregator_making_string )
   Using Day as value column: use value.var to override.
 ID  .
   1  1 1, 2, 4, 7
   2  2   2, 3
   3  3 1, 3, 4, 8

 In both of these, the three dots denote all arguments to the aggregator,
 as explained in Burns Statistics's http://www.burns-stat.com/the-
 three-dots-construct-in-r/ . My first aggregator sums them; my

GGobi needs a 64 bit binary before we can get rggobi available on Windows
again.

 You need to set some environment variables: study the rggobi sources for
 what. E.g. I bet GGobi is not installed in the root, so -I/include/ggobi
 will not work.

Re: [R] figure margins too large in RGtk2 drawing area as cairo device - why?

[Michael Lawrence]

Hi Mark,

This comes down to the way that GTK+ allocates size to its widgets. The
allocation of a widget is initialized to have a width and height of 1. When
a child is added to a visible parent, the parent will execute its lay out
algorithm and allocate a certain amount of space to the widget. The widget
is notified of this change via an event that arrives after an iteration of
the event loop. An event loop iteration may be forced in a number of ways;
you've discovered the Sys.sleep() method.

However, it is generally not good practice to show a container before
adding its children, unless widgets are being added in the middle of a
session, which is rare. If you were to instead do something like this:

win = gtkWindow(show = FALSE)
win$setDefaultSize(500, 500)
da = gtkDrawingArea()
asCairoDevice(da)
win$add(da)
win$showAll()
plot(1:10)

Then GTK+ will correctly initialize the allocation of the widget, I think
even before a configure event is received. The above approach is my
recommended solution to your problem.

Thanks,
Michael

 I did the following: restart R and run the same code with and without a
 minimal system pause (Sys.sleep) after the line that adds the device to the

 Adding a pause will make it work, though I do not understand what is
 happening here. Note the different settings of par(din).
 This is probably not the expected behavior, I guess.
 Any ideas why this is the case? It seems as if din is not adjusted on
 time? Might that be?

  The par settings returned in the example are the defaults, so no

  Also, it does not matter what size the drawing area is set to (e.g.

  What about din and mai? The margin problem usually means that the

Re: [R] changing the drawing context using Cairo and RGtk2

[Michael Lawrence]

On Wed, Mar 7, 2012 at 1:47 PM, Mark Heckmann mark.heckm...@gmx.de wrote:

 Michael, thanks for your answer!

 The attribute solution has its problems though.
 First, how it will work:

 foo - function(){
   w - gtkWindow()
   da - gtkDrawingArea()
   w$add(da)
   asCairoDevice(da)
   print(dev.cur())
   gObjectSetData(da, dev.number, data = dev.cur())
   dev.set(gObjectGetData(da, dev.number))
   par(mar=c(0,0,0,0))
   plot(1:10)
 }

 The problem arises when I try to convert a drawing area to Cairo WITHIN
 another function.
 Than dev.cur() does not work as I expected. The device returned is the
 Null device instead.

 foo_2 - function(){
   da - gtkDrawingArea()
   asCairoDevice(da)
   print(dev.cur())# NULL DEVICE!
   gObjectSetData(da, dev.number, data = dev.cur())
   da
 }

 foo - function(){
   w - gtkWindow()
   e - environment()
   da - foo_2()
   w$add(da)
   dev.cur()
   dev.set(gObjectGetData(da, dev.number))
   par(mar=c(0,0,0,0))
   plot(1:10)
 }

 As in most cases the code for creating and converting a drawing area is
 not located in the main function but rather inside a handler etc. the
 attribute solution will often work.
 Or am I missing something here?


The R graphics device is not actually created until the widget is realized
(in GTK terms), because it cannot plot anything until then. The difference
in the code above is that in the first case you are adding the drawing area
to the visible window (and thus realizing it) prior to calling dev.cur().
The order is reversed in the second case.

Michael

I think this problem is very general when working with RGtk2, Cairo and
 multiple drawing areas (e.g. on notebook tabs).
 So I wonder if there is another way to go about it. Do you have an idea?

 Thanks in advance

Re: [R] RGtk2: How to overlay a gtkDrawingArea with a button or any other widget?

[Michael Lawrence]

Sorry for the late reply to this one. You'll need to make sure that the
drawing area is realized prior to plotting, i.e., it should be in a visible
container. Also, since you are using GtkFixed, you will need to set an
explicit size request on the drawing area (otherwise it has zero area).

Re: [R] RGtk2 problems

[Michael Lawrence]

The gain from updating will be that RGtk2 now looks in a specific (internal)
place for the libraries, so you should no longer need to worry about library
conflicts and PATH settings. In theory.

 Thank you for the response and I am sorry about the html--will
 remember next time.
 The version of RGtk2 installed is 2.20.8 I installed it through R from
 CRAN repository.
 I believe that the problem is that during the installation the
 environment variable GTK_BASEPATH was set to some other location than
 where GTK+ was installed--overwritten by the R installation process. I
 found this after I fixed the issue by copying the libraries into R
 \bin. This is probably not the best solution but it works. I will be
 updating R soon to 2.14 when it comes out and hopefully things will
 work better now that I have the environment variable pointing to the
 right place for the GTK+ libraries.

Re: [R] Failing to install {rggobi} on win-7 R 2.12.0

[Michael Lawrence]

Hi Tal,

Thanks for working through this. GGobi needs to be rebuilt for the new
version of GTK+. I'm probably the person to do that, but my time is short
these days. I'll try to get to it soon. The new binary will just include the
necessary DLLs, so that this GTK+ installation step is unnecessary.

 Dear Prof Brian Ripley and others,

 After (finally) checking again, I found that ggobi doesn't work with the
 newer GTK (probably needed for R 2.12.0).

 Here is the results of my experimentations:


 *What works:*
 Installing ggobi and the GTK (version 2.12.9) provided on:
 http://www.ggobi.org/downloads/
 Will *work* with R 2.11.1 + rggobi (version 2.1.14)
 (notice that the newest version 2.1.16, is not available for windows users.
  And the newer version 2.1.16-3 is not available on CRAN:
 http://cran.r-project.org/web/packages/rggobi/index.html)


 *What doesn't work:*
 Trying this with R 2.12.0 with rggobi (version 2.1.16-3), will *crash* with
 the error:

 the procedure entry point g_malloc_n could not be located in the
 dynamic link library libglic-2.0-0.dll


 When then trying to install gtk+ from the dialog box offered, then it
 downloads GTK (version 2.22.0 instead of 2.12.9) from here:

 http://downloads.sourceforge.net/gtk-win/gtk2-runtime-2.22.0-2010-10-21-ash.exe?download
 '

 After doing this, ggobi (not rggobi) itself, won't run. It will crash with
 the error:

 the procedure entry point g_assertion_message_error could not be located
 in
 the
 dynamic link library libglib-2.0-0.dll


 Trying then to insert the dll's from the packages Prof Brian Ripley
 suggested (libxml2.dll and iconv.dll) won't fix the problem.
 Also using the libglib-2.0-0.dll from the old GTK package won't help.
 Also, reinstalling ggobi won't work.



 Any suggestions on how to make ggobi work with the newer version of GTK ?

 Thanks,
 Tal

Re: [R] RGtk2 compilation problem

[Michael Lawrence]

On Thu, Jan 6, 2011 at 8:53 AM, Prof Brian Ripley rip...@stats.ox.ac.ukwrote:

 You need RGtk2 2.20.7 which is now on CRAN.  Others have seen this, but it
 has taken a while to track down the exact cause.

 The diagnosis was that ML used a recent GNU tar which created a tarball
 with hard links that R's untar was not prepared to deal with. We consider
 that is a bug in GNU tar, but untar() has been updated in R-patched to cope.


After a lot of back and forth with the GNU tar guys, it turns out they do
not consider this to be a bug. I had to refresh my knowledge of hard linking
to understand. A hard link is from a file name to the actual inode in the
file system. Typically every file has a single hard link (the name of the
file). The -h option used to resolve a symbolic link differently, based on
whether the hard link count of the target was 1 or =2. This was practically
useful in my mind, because symlinks to any files without any explicitly
added hard links would become a regular file in the archive. They have now
dropped this distinction, calling it an inconsistency (apparently other
implementations of tar have never made such a distinction). So symlinks now
become hard links in the archive (as long as the target is in the archive).
We may need to keep the fix in untar() to handle this. Either way, RGtk2
2.20.7 should work now.

Thanks,
Michael


 If you have such a tarball, try setting the environment variable
 R_INSTALL_TAR to 'tar' (or whatever GNU tar is called on your system) when
 installing the tarball.

 For those packaging source packages: in the unusual event that your package
 sources contains symbolic (or even hard) links, don't use GNU tar 1.24 or
 1.25.

 Yes, this is another issue that arose with R 2.12.0 and discussed on the
 rattle-users mailing list (http://groups.google.com/group/rattle-users).
 Be
 sure to use the newest version of Rattle (currently 2.5.47) where this has
 been fixed. I've not worked out why, but if the XML package is loaded
 before the RGtk2 package we see this error, but not if RGtk2 is loaded
 first. Rattle now loads RGtk2 first.


The reason is that the zlib1.dll provided with XML is older than the one
expected by the automatically installed GTK+ binaries. I'm working on a way
to make installing RGtk2 easier for others.

[R] [R-pkgs] RGtk2 2.20.x

[Michael Lawrence]

This is to announce the release of the RGtk2 2.20.x series. RGtk2 is an
interface between R and the GTK+ GUI toolkit and friends. The new release
updates the bindings to support up to GTK+ 2.20 (and remains backwards
compatible to 2.8). Previously, the interface supported only up to GTK+
2.12, which is several years old.

New features in GTK 2.20 (relative to 2.12) include:

* GtkInfoBar widget: Displays transient popup notifications, generally at
the bottom of the window (near the status bar).
* Off-screen rendering of widgets, e.g., automatically save a widget or
visualization to disk.
* GtkSpinner: Animated widget for indicating activity
* GtkToolPalette: Essentially a multi-row toolbar with drag and drop of
toolbar items between the palette and other tool item containers.

The bindings to Pango and Cairo were also updated to the latest stable
versions.

RGtk2 also adds a new library to its interface: GIO (2.22), a low-level
library supporting asynchronous streaming I/O, mounting of volumes,
networking, etc. Might be useful.

There is also a new mode of error handling available, that is disabled by
default. By setting the option RGtk2::newErrorHandling to TRUE, errors in
the libraries will result in errors in R (instead of warnings), and the
error object is no longer returned, which often simplifies return values by
no longer requiring a list to hold both the error and the original return
value. This is probably a more sensible strategy.

Windows users: The new binaries for Windows are being built against 2.20, so
you'll need to get GTK+ 2.20 (or higher, 2.22 is released but does not
really add any new features) for Windows at:
http://gtk-win.sourceforge.net/home/index.php/en/Downloads.

Thanks,
Michael

Re: [R] Zoom in in a plot

[Michael Lawrence]

You might want to check out the Qt stuff we've been working on. The qtutils
package has a graphics device that supports zooming and other fun stuff.
Also, qtpaint provides a flexible low-level engine for interactive graphics.

See: http://github.com/ggobi/qtpaint and http://github.com/ggobi/qtutils.
They require qtbase from: http://github.com/ggobi/qtbase.

They require the installation of Qt: http://qt.nokia.com. Still working on
Windows support.

 For a quick exploration of the plot you can use the zoomplot function in
 the
 TeachingDemos package.  But for production graphs it is better to
 explicitly set
 the xlim and ylim parameters in creating the plot up front.

Re: [R] Problem loading RGtk2 (iconv.dll)

This sounds like a DLL conflict to me. For example, do you have Matlab
installed? Sometimes if Matlab is on the PATH, the DLLs can conflict.

 Hello dear R-help list and Michael Lawrence.

 I wish to use GTK with R.
 I installed the newest RGtk2 and GTK from:

 http://sourceforge.net/projects/gladewin32/files/gtk%2B-win32-devel/2.12.9/gtk-dev-2.12.9-win32-2.exe/download
 on the path:
 C:\Program Files\Common Files\GTK\2.0\

 And followed the instructions on the installation manual for RGtk2, and
 added the line:
 GTK_PATH=C:/Program Files/Common Files/GTK/2.0
 To the
 etc/Renviron.site
 file.


 Yet when I come to  load the package via require(RGtk2), I get the
 following *error massage*:

 the procedure entry point libiconv_set_relocation_prefix could not be
 located in the dynamic linke library iconv.dll


 And then (in the R console) I get:
 Loading required package: RGtk2
 Error in inDL(x, as.logical(local), as.logical(now), ...) :
   unable to load shared library 'C:/Program
 Files/R/library/RGtk2/libs/RGtk2.dll':
   LoadLibrary failure:  The specified procedure could not be found.

 The interesting thing is that after I install GTK (through the
 auto-install), then RGtk2 loads without error in R.  But if I try to run
 something, for example:
 demo(alphaSlider)
 I will get the error massage:
 Error in .Call(name, ..., PACKAGE = PACKAGE) :
   C symbol name S_gtk_window_new not in DLL for package RGtk2


 Upon restarting R, again, I wouldn't be able to use  require(RGtk2)

My only guess is that installing RGtk2 from source is only possible if you
have the gtk-devel package installed, i.e., the one with the headers.
Otherwise, you'll need the r-cran-rgtk2 binary.

 After the first attempt ended up with two of the four dependencies

Using a root terminal session I went back into R and ran

Re: [R] RGtk2:::gdkColorToString throws an error

Actually, the problem is more likely that RGtk2 is not built against GTK+
2.12 on Windows. I assume you're using an up-to-date version of R. I'll ask
Uwe about getting a newer version of GTK+.

  To embed a GTK widget into gWidgets isn't too hard, just call the add
 method.
  I'm not sure how  to get the GTK object you want from the ggobi
  interface. Below is an example that you might be able to modify:
 
  ##
  library(RGtk2)
  library(rggobi)
  library(gWidgets)
  options(guiToolkit=RGtk2)
 
  ## ggoobi object
  x - ggobi(mtcars)
 
  ## grab child from main window. Modify (how?) to get
  ## other widgets
  toplevel - ggobi_gtk_main_window(x)
  child - toplevel[[1]] Â # toplevel has only one child
  toplevel$remove(child) Â # remove child if keeping toplevel
  toplevel$destroy() Â  Â  Â # or destroy if not
 

 ## add to a gWidget instance using gWidgetsRGtk2:
  w - gwindow(A gwidget's window)
  g - ggroup(cont = w, expand=TRUE)
  add(g, child, expand=TRUE)
 
  --John
 


 Here is some code to grab the display for a new display. I don't know
 how to get the initial display or even how to suppress it, but I'm
 not a ggobi user at this point.

 library(RGtk2)
 library(rggobi)
 library(gWidgets)
 options(guiToolkit=RGtk2)

 x - ggobi(mtcars)
 ## not sure how to get the initial display,
 ## here we create a new display and move that
 disp - display(x[1]) ## see display.GGobiData


Try

plotWidget - display(x[1], embed=TRUE)

That will give you a display widget without hacking up the GGobi GUI.

## find table in the display heirarchy
 table - disp[[2]]

 ## plot is third child (rulers are first two)
 plotWidget - table[[3]]$getWidget()
 table$remove(plotWidget)
 ## hide window that held display. Destroy() causes errors
 disp$getParent()$hide()

 ## now we need to declass things so that gWidgets will
 ## recognize. The S3 classes from RGtk2 that gWidgets
 ## knows about are declared in package (should be
 ## dynamic, but aren't)

 class(plotWidget) - class(plotWidget)[-(1:3)]

 w - gwindow(A gwidget's window)
 g - ggroup(cont = w, expand=TRUE)
 add(g, plotWidget, expand=TRUE)

 Hi All...

 I¹m trying to build a small demo using gWidgets which permits interactive
 scaling and selection among different things to plot.  I can get the
 widgets
 for scaling to work just fine.  I am using gcheckboxgroup to make the
 (possibly multiple) selections.  However, I can¹t seem to figure out how to
 properly define the gcheckboxgroup; I can draw the widget properly, I think
 my handler would use the svalue right if it actually received it.  Part of
 the problem is using the index of the possible values rather than the
 values
 themselves, but I'm pretty sure this is not all of the problem.  I've been
 unable to find an example like this in any of the various resources I've
 come across.

 BTW,  report.which is really only there for troubleshooting.  It works to
 return the values, I can't get it to return the indices, which are probably
 what I need in this case.

 A demo script is at the bottom and the error is just below.

  tmp - gcheckboxgroup(stuff, handler = report.which, index = TRUE,
 + checked = c(TRUE, FALSE, FALSE, FALSE, FALSE), container = leftPanel)


The above code should define the gcheckboxgroup.


  add(tmp, value = 1, expand = TRUE)


I'm not sure what you are trying to add here.



 Error in function (classes, fdef, mtable)  :
  unable to find an inherited method for function .add, for signature

 This error suggests that I don't have a method - I agree, but I don't know
 what goes into the method for gcheckboxgroup.

 For the sliders, it's clear to me how the actions and drawing of the
 widgets
 differ, but not so for gcheckboxgroup.

Re: [R] Programmatically copying a graphic to the clipboard

Possible using RGtk2. Just need to get it into a GdkPixbuf. See
gtkClipboardSetImage(). To get a graphic as a pixbuf, you can use
cairoDevice (drawing to a GdkPixmap and copying over), or output the graphic
to a temporary file and read it back in.

Re: [R] Gtk objects disappears

I would recommend just running gtkMain(), so that GTK+ blocks R. Then you

 Until now, I bypass this problem using the following commands:

 But it is not really satisfactory and the tcltk Box cannot be

 Any idea?

 tutorials (which have C code). This is a little problematic, but has
 helped quite a bit in getting me started.

 I would like to create a GUI for file selection, which then displays
 the column names from the selected file, and provides the user with
 checkboxes with each column name for the user to select. Two columns
 of check boxes (Factor Type, Numeric Type) and one column of names is
 what I would like to display.


This would use what is known as a GtkTreeView widget. There is RGtkDataFrame
object that will tie an R data frame directly to a GtkTreeView as its
GtkTreeModel. See help(RGtkDataFrame). Using a GtkTreeView is pretty
complicated, but powerful. Basically, you create your RGtkDataFrame from an
R data.frame and pass it as the model to the gtkTreeView constructor. You
then need to add columns to the tree view to map the data to the view. Your
best bet is to check out the demos included with RGtk2, like editableCells
and treeStore.



 Moreover, I am planning to create a GUI tool that would have tabs in a
 notebook layout, each tab providing a certain functionality, beginning
 from basic charting of data, and going on to applying regression
 models and such on the data.


help(GtkNotebook)



 This requires extensive knowledge in components that RGtk2 provides
 which could be implemented for the task outlined above. I have looked
 at the omegahat.org examples, but would like to see examples for such
 simple tasks as to how one could create a drop down list of column
 names to choose for x axis and another drop down allowing the choice
 of y axis, etc.


See help(GtkComboBox) and gtkComboBoxNewText().



 Having made the choice to use RGtk2, I would  appreciate if users
 could share their RGtk experience with me.


I wrote a paper on RGtk2, but for some reason it has never been published.
Probably time to write a book.

Re: [R] GTK Tooltips under Linux

 Dear all,

 I want to set tool-tips for a gtkButton. I use the following code
 which works under Windows. However, it doesn't work under Linux. Any

Unfortunately, on platforms besides Windows, the event loop runs via an
input handler connected to X11. If you're waiting for a tooltip to show up,
there's obviously no input, so the event loop is not iterated.

I think I could fix this by creating a separate thread that writes to a file
descriptor connected to an input handler. I'll try to do that.

 I was wondering whether there is any interface to use processing (

Nothing direct, to my knowledge.

As far as I know, Processing is a high-level language on top of drawing and
user interface libraries. R is already a nice language for data analysis, so
there have been many efforts to connect R to existing libraries for doing
Processing-like things. Examples include iPlots, rggobi, RGtk2, and there
are several systems currently under development.




 If so could somebody point me to relevant ressources?

 If not, are there any attempts to build such an interface / package?

Re: [R] Building GUI for custom R application

 HI R users,
 I would appreciate information/examples/suggestions on building GUIs
 for R applications.
 I am currently working on a project that would require the following
 functionalities :

 1) Display a  window to the user. Provide a function to scan local
 drive and choose dataset file.
 2) Display the column names for the user to choose the dependent
 variable and the independent variables.
 3) Fit regression and display statistics.

 While researching the possibility of creating a GUI which would allow
 for the above mentioned computations, I came across:

 1) rpanel: Simple Interactive Controls for R Functions Using the tcltk
 Package
 Found In: Journal of Statistical Software, January 2007, Volume 17, Issue
 9.


 2) Putting RGtk to Work, James Robison-Cox
 Found In:Proceedings of the 3rd International Workshop on Distributed
 Statistical Computing (DSC 2003),March 20–22, Vienna, Austria ISSN
 1609-395X
 http://www.ci.tuwien.ac.at/Conferences/DSC-2003/

 Item 2 provides an example of creating a regression application with
 slider controls for a parameter in loess function used in the example
 application in that paper.
 For documentation on RGtk the author recommends reading the Gtk
 tutorial and documentation. I seem to have difficulty in making sense
 of the Gtk documentation since most of it is in C and documentation is
 available for use of Gtk with Perl and Python. I am not a
 C/Perl/Python programmer.


RGtk2 is completely documented within the R help system, with all code
examples converted to R code. There are also a couple dozen demos. For a
simple GUI like the one above, try gWidgets. The pmg package implements a
gWidgets GUI that includes functionality much like what you describe.



 Moreover, I am creating a Windows Application and is using RGtk2 the
 only way to create a GUI for an R application?
 Or should I use the the VB approach and create the GUI separately and
 call R scripts where required to do the back-end computation?

 Another approach (to make the visualization more rich and dynamic) is
 to use Adobe FLEX front end and communicate with R using the RSOAP
 library. There is very sparse documentation relevant to using RSOAP. I
 have not been able to find examples or tutorials using RSOAP. Any
 information in this regard will be highly appreciated.

 The Biocep project provides 'R for cloud computing' but unfortunately
 I have not been able to extract relevant 'juice' from their webpage.
 What i did get is their R workbench, but that has not answered my
 above mentioned queries.

Well, SSOAP is (the last time I checked) just a SOAP client. rsoap (if we're
talking about the same package) is actually a python SOAP server that
communicates to R via rpy.

You might want to check out the RWebServices package in Bioconductor. I
think it uses Java for its SOAP handling.

Just to be sure you're aware, there are packages for chromatograpy and mass

 Hi,

 I'm able to match peaks when they are chromatographed with the same method,

 I made some dummy chroms with R, which mimic my actual datasets, to play

 Mark,

 The first thing I would look at is whether there are any *-dev packages
 in
 synaptic for the libraries etc that are 'missing'.  These -dev packages
 contain
 the header files and are not necessary for running the application, but are
 necessary for installing other apps from source that interact with them.
 This is a surprisingly little-advertised issue with Linux packaging that I
 found
 out about from the R installation manual.


Just to be a bit more specific, for building RGtk2 and rggobi you'll need
gtk-dev(el?) and libxml2-devel which should install all the other devel
dependencies. It's kind of strange that the GGobi package installs its
header files (it is implicitly a devel package), but it does not bring in
the devel packages of its dependencies.

But aren't there binary Ubuntu/Debian packages on the repository for RGtk2
and rggobi?

 Try installing gWidgetstcltk. That will allow you to use gWidgets with the

Perhaps the gWidgets package should prompt the user to install one of these?

  Subject: [R] Creating GUIs for R
 
  Hi all,
 
  I have looked around for help on creating GUIs for R, but haven't found
  anything.  I would be interested in any advice or webpages that have
  information on the best language, tutorials etc. for creating simple
 GUIs.
  Mainly I want to do this as a heuristic exercise.
 
  Thanks for any help.

Re: [R] crashes while using Rattle (GTK+)

Just saw this one. This should be fixed in RGtk2 2.12.7 on CRAN.

 and then R crashes. I tried to reinstall R, reinstall all packages (i have
 all dependent packages installed), I was looking on GTK+ pages and Google
 but I only found similar post without an answer.

 I think that problem lies in GTK. But I don't have any idea how to get the
 things working.

 Please help !

Rattle should have no problems on Vista, especially with the latest GTK+

A general comment though: learning the command line of R is probably worth
the time investment, unless you have a very specific task in mind and there
is an existing GUI that supports that task.



 The Rattle log file auto generates the code, so it can be of some

Re: [R] playwith package crashes on Mac

[Michael Lawrence]

For some reason, cairoDevice has been crashing the Mac for a while. It has
something to do with the rotation of text through Pango. That's all I've
been able to determine. Kind of tough without access to a Mac... but it DID
work once upon a time..

2008/7/15 Felix Andrews [EMAIL PROTECTED]:

 Dear Professor Kubovy

 I do not have a Mac to test it on, but please try this:
 library(cairoDevice)
 Cairo()
 grid::grid.newpage()

 I expect that you will see a similar crash; if so, it would seem to be
 a problem with your GTK+ libraries. I have heard that you need to have
 Apple X11 installed (from MacOS system CDs?) for RGtk2 to work. But I
 am not sure whether that advice is still current.

 Hope that helps.

Re: [R] Unexpected behaviour in reading genomic coordinate files of R-2.7.0

[Michael Lawrence]

This is not really addressing your problem, but I thought you might want to
know that the rtracklayer package in Bioconductor already supports parsing
BED files, as well as GFF and WIG. It's main purpose is to load the tracks
into genome browsers, like UCSC.

 Great R people,

 I have noticed a strange behaviour in read.delim() and friends in the R
 2.7.0 version. I will describe you the problem and also the solution I
 already found, just to be sure it is an expected behaviour and also to tell
 people, who may experience the same difficulty, a way to overcome it.
 And also to see if it is a proper behaviour or maybe a correction is
 needed.

 Here is the problem:
 I have some genomic coordinates files (bed files, a standard format, for
 example) containing a column (Strand) in which there is either a + or a
 -.
 In R-2.6.2patched (and every past version I have used) I never had problems
 in reading them in, as for example:
  a - read.table(coords.bed, skip=1)
  disp(a)
 class  data.frame
 dimensions are  38650 6
 first rows:
   V1V2V3V4 V5 V6
 1 chr1 100088396 100088446  seq1  0  +
 2 chr1 100088764 100088814  seq2  0  -

 If I do exactly the same command on the same file in R-2.7.0 the result I
 obtain is:
  a - read.table(coords.bed, skip=1)
  disp(a)
 class  data.frame
 dimensions are  38650 6
 first rows:
   V1V2V3V4 V5 V6
 1 chr1 100088396 100088446  seq1  0  0
 2 chr1 100088764 100088814  seq2  0  0

 and I completely loose the strand information, they are all zeros! I have
 also tried to put quotes around + and - in the file before reading it,
 to set in read.table() call stringsAsFactors=FALSE, to set encoding to a
 few different alternatives, but the result was always the same: they are all
 transformed in 0.

 Then I tried scan() and I saw it was reading the character + properly:
  scan(coords.bed,  skip=1, nlines=1, what=ch)
 Read 6 items
 [1] chr1 100088396100088446.00 seq1 0  [6]
 +
 ...my conclusion is that the lone + or - are not taken as characters
 in the data frame creation step, they are taken as numeric but, being
 without numbers are all converted to 0.
 Is it correct if this behaviour happens also if they are surrounded by
 quotes?

 Anyway, my temporary solution (which works without the need of changing the
 files) is:
 a - read.table(coords.bed, skip=1, colClasses=c(character, numeric,
 numeric, character, numeric, character))
  a[1:2,]
   V1V2V3V4 V5 V6
 1 chr1 100088396 100088446 seq1  0  +
 2 chr1 100088764 100088814 seq2  0  -

 Another way to avoid loosing strand information was to manually substitute
 an R to - and an F to + in the file before reading it in R. But it
 is much more cumbersome since the use of + and - is, for example, a standard
 format in bed files accepted and generated by the Genome Browser and other
 genome sites.

 Please let me know what do you think. Ps. I saw this first in the Fedora
 version (rpm automatically updated), but it is reproduced also in the
 Windows version.

 Thank you all people for your work and for making R the wonderful tool it
 is!

 Cheers,

 Margherita

Well running it within Emacs may explain it. We actually aren't spawning a

 Thanks for the good advice.


I am pretty sure what Paul is referring to is the graphics device stuff.
GGobi does not link against R anyway, so R would not be the problem here.

The reason rebuilding GGobi fixed it, is that your GGobi binary was linked
against an old version of graphviz. The new version broke binary
compatibility, thus you needed to install a GGobi binary built against the
new version.

  In the R 2.7 release notes, there is a comment about a change in the

  relies on R.  If your R 2.7 was an upgrade, not a fresh install, it
  could explain why this is happening.  If there's some old library or R
  package sitting around, it could account for this.
 
  The part that concerned me about the R release note is that they don't
  give a very clear guide on how far back in the toolchain we are
  supposed to go.  Certainly, ggobi has to be rebuilt from scratch.  But
  are any of the things on which ggobi depends needing recompliation as

Re: [R] Annoying bug in package cairoDevice

[Michael Lawrence]

Sorry about this. cairoDevice 2.8 (just uploaded to CRAN) should fix this
problem.

On Tue, Apr 29, 2008 at 1:08 PM, Josh Gilbert [EMAIL PROTECTED] wrote:

 I sent this to R-Help and the listed maintainer of cairoDevice, I hope
 that was the right thing to do.

 For some reason, Cairo_png puts a box around a figure when you call
 plot.new. It looks like box was called with black and a transparent
 background. Example:
  library(cairoDevice)
  Cairo_png('cairo.png')
  plot.new()
  dev.off()
 null device
   1

 The boarder is narrow, so it's hard to see with a stand-alone image
 viewer. If you paste the png onto a white background it's quite clear.

 Admittedly, the default for par(bg) is transparent, par(bty) is o
 and par(col) is black. However, this behavior is not consistent with other
 devices (such as png in grDevices even if I set par(bg=white)). Also,
 Cairo_png draws the box even when par(bty=n).

 I just tested this on Debian with version 2.6 of cairoDevice. I've also
 observed this behavior on Windows and it's not a new problem.

 The only workaround I've found is to call
  Cairo_png()
  par(col=white)
  setHook(plot.new, function() par(col=black))
  plot(...)

 As far as I'm concerned, this is a serious bug, it's a real problem when
 creating figures for publication. I'd like confirmation that this is, in
 fact, a bug as I haven't seen much documentation for standards for devices.
 I suspect that it's a shallow bug, but I've never seen the code for plot.new
 nor do_Cairo so my suspicion may be more hope than insight.

Re: [R] GUI developement / Matlab

 Hi there,

 I was wondering whether there are flexible packages available with which
 you
 can create user interfaces? (I've read about gWidgets!?)


gWidgets provides an easy to use API for developing GUIs in R. It's an
abstraction over several actual toolkit bindings (tcl/tk, RGtk2, and
rJava/Swing). The best supported implementation is based on RGtk2. Depending
on the level of control and features you require, you might have to resort
to direct use of RGtk2, which is a complete low-level binding to the GTK+
toolkit.


 For example in Matlab you can even create stand alone applications. Is it
 also
 possible for R in the same extend? Of course it should be platform
 independent
 if possible...


tcl/tk, GTK+, and Swing are all cross-platform toolkits used for developing
stand-alone applications. Developing your GUI in gWidgets will allow the
user to choose among those three. But for a true stand-alone application
(without running R directly) you'll probably want to develop the application
and its GUI in another language and then delegate to the R library for
certain tasks.



 And then I would like to know from people who know R as well as Matlab.
 What
 would you see as advantages and disadvantages comparing both systems (from
 your
 personal needs). I've learned a little bit of R and I like the concept but
 I
 don't know much about Matlab. (I hope this question is not too off topic?)

 Thank you!

Re: [R] RGTK2 and glade on Windows - GUI newbie

That would be a good idea. I'm finishing up a much more comprehensive guide
that will become available soon.

Thanks for the suggestion,
Michael

2008/2/14 Felix Andrews [EMAIL PROTECTED]:

 I just discovered a good introduction to the RGtk2 package:
 RShowDoc(overview2, package=RGtk2)

 I have been using RGtk2 for over a year without knowing about that,
 and struggling with the API documentation, so can I suggest that it be
 mentioned somewhere prominent? i.e. put it on the project web-page,
 and make it a vignette so that it appears on the CRAN package page.

 Cheers,
 Felix


 2008/2/11 Felix Andrews [EMAIL PROTECTED]:
  Yes, a GUI based on GTK+ (with or without Glade) will work on Windows
 XP.
 
   If what you want to do is relatively straightforward (say, without any
   fancy formatting, or advanced event handling) then you should consider
   gWidgets. Look at the vignette in the gWidgets package.
 
   If you do decide to go with RGtk2 directly rather than gWidgets, look
   at demo(package=RGtk2). If you are using Glade, you might want to
   look at the source code for Rattle, which is a GUI built with Glade:
   see http://rattle.googlecode.com/
   and http://datamining.togaware.com/survivor/Installation_Details.html
   (Another example is hydrosanity: http://hydrosanity.googlecode.com/)

 In your example, can you think of a way to have a cancel button that

  Hello,
  I'm trying to make a graphical interface for an R function
  I've written. A common use for the function is to call it with
  specific parameters, and then watch the output as it evolves.
  There's not necessarily a logical stopping point, so I usually
  use ctrl-C when I'm done to stop it.
  I've made a gWidgets interface to the function that gets some
  user info and then on a button click calls the function. The
  gWidgets window, however, seems to be frozen as long as the
  function is running, and the function output seems to be
  happening in the background in my R session, so ctrl-C (esc
  on the Mac GUI) does not work to stop it. I have to kill R
  entirely to stop the process.
  So after all that setup here is my question:
  Is there some way to have a gWidgets window interrupt a
  function that it has called via a widget handler?
  Thanks,
  Peter

John might correct me, but I don't think that gWidgets supports this
level of markup. You might try using tcltk or RGtk2 directly (eg the
GtkTextView and GtkTextBuffer classes). It would be easy to get the
index of a selection in the buffer. See the function
gtkTextBufferGetSelectionBounds() in RGtk2.

 2, I would like to arganize the codes like a tree. The code tree and

 3, In the coding buttong, how can I avoid using - in handler function.

   gWidgets is quite good. However, I want to get the selection text chunk as

obj-gtext(cont=T)
svalue(obj,drop=T)

svalue(obj,drop=T,index=T)
   [1] cde
  
 
 
 
  The svalue method has the index argument for the widgets where you might 
  want to
  return the  index or value such with a radio button group or combobox. For
  gtext, the drop argument when TRUE returns just the text selected by the 
  mouse,
  otherwise the entire text buffer is returned.
 
  library(gWidgets)
  options(guiToolkit=RGtk2)
  obj = gtext(sadfsad,cont=T)
  svalue(obj)   ## returns: sadfsad\n
  svalue(obj,drop=TRUE)  ## returns  
  ## now highlight some text
  svalue(obj,drop=TRUE) ## returns dfsa

Re: [R] Graphics device storable in a variable

[Michael Lawrence]

This is possible using the cairoDevice package and RGtk2.

Turning an R graphic into a raw vector of bytes:

library(cairoDevice)
library(RGtk2)

# create a pixmap and tell cairoDevice to draw to it

pixmap - gdkPixmapNew(w=500, h=500, depth=24)
asCairoDevice(pixmap)

# make a dummy plot

plot(1:10)

# convert the pixmap to a pixbuf

plot_pixbuf - gdkPixbufGetFromDrawable(NULL, pixmap, pixmap$getColormap(),
0, 0, 0, 0, 500, 500)

# save the pixbuf to a raw vector

buffer - gdkPixbufSaveToBufferv(plot_pixbuf, jpeg, character(0),
character(0))$buffer

###

Then you can send buffer to your database, or whatever. Replacing jpeg
with png will probably produce png output.

 You might try looking at the tkrplot package, it uses win.metafile and
 captures the graphics device into a variable (which is then put into a
 tk lable, but you could probably do something else with it).

  Subject: [R] Graphics device storable in a variable
 
  I'm using R embedded in PostgreSQL (via PL/R), and would like
  to use it to create images. It works fine, except that I have
  to create every image in a file (owned by and only readable
  by the PostgreSQL server), and then use PostgreSQL to read
  from that file and return it to the client. It would be much
  nicer if I could plot images into an R variable (for
  instance, a matrix), and return that variable through the
  PostgreSQL client. Leaving aside the details of returning the
  data to PostgreSQL (which I realize are beyond the scope of
  this list), I envision R code along the lines of the following:
 
  # Create a png device, a handle to which is stored in myDevice
   myDevice - png.variable(height = 1280, width = 1024, bg = white)
  # Plot some data into the current device
   plot(myX, myY, col=red)
  # Finalize
   dev.off()
  # Print out the contents of myDevice
   myDevice
 
  ...and the data would print out just like any other matrix or
  class or whatever type myDevice actually is.
 
  So my question is does such a thing already exist? I know
  about piximage, but apparently I have to load image data from
  somewhere for it to work; I can't use plot(), etc. to create
  the piximage data. GDD would be a nice way to do it, because
  GD libraries are widely available for use with other
  languages I might use with PostgreSQL and PL/R (for instance,
  Perl would talk to PostgreSQL, call a PL/R function to use R
  to return an image, which Perl would then process further),
  but GDD requires temporary files as well, as far as I can
  see. Thanks for any help anyone can offer.

Re: [R] jEdit for R

Tinn-R probably loads faster, since it doesn't have the overhead of Java. As
far as stability, I haven't used Tinn-R enough to compare. I use jEdit for
my daily work, all day long, for the past 6 years, and I can't remember it
ever crashing on me.

 I think a better idea would be to make a jEdit plugin
 that embeds an R console component (perhaps the one from
 JGR, but the last I checked it was not embeddable,
 unfortunately). Anyway, it would be easy enough to roll your
 own by extending the existing jEdit Console plugin using JRI.
 I would have done that ages ago, but I'm still hoping that
 JGR could be leveraged in some way.

 In my opinion, jEdit has a very clean design (at both the UI
 and the API level) as do several of the important plugins
 (ie Console). One can actually run R inside the jEdit console,
 but it does not echo your commands, which hinders its usability.

 I haven't used Tinn-R much since it is not cross-platform.
 Also, I prefer to use the same editor for all my work, beyond R,
 and I'm not sure if Tinn-R would be up to that task (but as
 I've said I haven't used it much).

 If anyone wants to work with me on providing an R support
 plugin for jEdit, I'd be open to starting the project. I've
 already written a document with various ideas, which goes far
 beyond simply embedding R. The editor-centric mode of using
 R is obviously very popular and useful, but, at least in my
 opinion, no editor does a great job at it on all platforms.

 Hi Rob,

   I eventually switched to Tinn-R, which is an editor customized for
 R
 (although it can be used for other languages) and does provide the
 connection to R you are looking for.  Also (I think) loads faster
 and it
 is more stable than jEdit.

Re: [R] R CMD build not excluding .svn

[Michael Lawrence]

Thanks for the help. I looked into it further and noticed that the src/RGtk2
directory was actually a symlink. The perl find() does not follow symlinks,
as invoked, but tar, as invoked, does. Thus, when the tar/untar effectively
copies the files, there is a mismatch with the exclude paths.

Is there some reason why the exclude paths cannot be calculated on the
untar'd version rather than the original package directory? If this sounds
reasonable, I'll submit a patch.

Thanks,
Michael

 Pretty unlikely.

[R] R CMD build not excluding .svn

[Michael Lawrence]

Hi,

In my package RGtk2, there's a directory called 'src/RGtk2' that contains,
like all the other directories in the package, a '.svn' directory. It seems
that R CMD build is somehow missing that one '.svn' in 'src/RGtk2', even
though it excludes all the other instances of '.svn'.

I've tried putting 'src/RGtk2/.svn' into the .Rbuildignore, but it does not
have any effect. I've also looked into the R CMD build script, but I can't
find where this problem might occur (but then again, perl is not exactly my
thing). Perhaps it has something to do with having a directory with the same
name as the package under the 'src' directory?

Re: [R] Cairo on windows

[Michael Lawrence]

On 9/27/07, Moisan Yves [EMAIL PROTECTED] wrote:

  My experience is that cairoDevice is a lot slower than Cairo,
 especially
 on Windows, and about equally flaky.  If you see how many layers are
 involved with Cairo on Windows you will not be surprised.

 Actually, I ended up trying to load deviceCairo simply because it was
 the only other package with the string Cairo in it besides Cairo
 itself ;-).  I suspected some interaction between the two libraries
 (deviceCairo and Cairo) so that's why I tried to load it hoping it would
 solve the flakiness of the CairoWin display.


My guess is the problem is due to an older version of GTK+. Although
cairoDevice only requires GTK+ 2.8.x (which is probably what you have
installed), the Windows binary of cairoDevice on CRAN is probably built
against GTK+ 2.10.x, just like RGtk2.

I've added a feature to cairoDevice and RGtk2 recently that will
automatically try to install the latest binary of GTK+ on Mac and Windows
when loading the library fails.

That said, I'd really like to merge cairoDevice (specifically the
RGtk2-embedding feature) with the Cairo package. Having one less package to
maintain would be nice.

 If all you need is semi-transparency support I suggest you try R 2.6.0
 RC
 which supports it in the windows() device.

 Thanx for the tip.
