Re: [R] Decision Tree
It is box.col= in prp(). fancyRpartPlot() in Rattle currently uses a fixed colour palette (something I should change). You could change it in a local copy of the fancyRpartPlot() code (see the line defining pals in the function): fancyRpartPlot I also give an example around page 33 of the Decision Trees chapter ( http://onepager.togaware.com/DTreesO.pdf) from the OnePageR website ( http://onepager.togaware.com).

Re: [R] Correlation in Rattle
Thanks for assisting here Paul. It turns out there is a bug in this release of Rattle. It is fixed and 2.6.19 will include the fix.

Tried usinging this two options on my 64-bit and 32-bit versions of R 2.15.0. Everything works fine. So I've at least been able to determine that there's nothing wrong with Rattle or with the combination of Ratttle and either the 64-bit and 32-bit versions of R 2.15.0. Beyond that, I'm not sure how much I can help you. Tried to think of silly things that could be happening. So, for example, if you don't click on Settings - Use Cairo Graphics Device, graphs generally get printed in R itself rather than on top of the Rattle graphical interface. If that were happening, then simply minimizing Rattle and looking at R would reveal the graph. I think this is unlikely though, given that you seem to be able to view graphs created using Distributions on the Explore tab. The only thing I can think of other than that is that maybe there is something wrong with your installation of R or with the process you're using to install Rattle. I don't recall there being anything tricky about installing either R or Rattle though. So I don't know what the problem could be. You could try contacting Graham Williams to see what he suggests. Or you could turn this over to an IT person if you have one. Sorry I can't be of more help.

So I changed to the weather dataset that comes with the software (which has fewer variables) and everything worked fine. Do you have a lot of variables in your data? What happens when you try this using the weather dataset? If you're unfamiliar with the weather dataset, you can load it by launching Rattle and then clicking execute. If there really is a problem, maybe uninstalling and reinstalling Rattle would fix it? For uninstall, you can use code like: remove.packages(rattle). For re-install, you could use code like: install.packages(rattle, dependencies = TRUE).

Re: [R] Launcher for Rattle?
Thanks to the advice from Brian, the next version of Rattle (2.6.7) will have the two bugs fixed. Then your launcher will simply need to be: sh -c 'R_DEFAULT_PACKAGES=rattle R $@' Regards, Graham On 16 April 2011 20:57, Iurie Malai iurie.ma...@gmail.com wrote: Thank you! Your code worked! I tested all the combinations and this shows that, in addition to the 'rattle', in this launcher code the 'utils' package is required, otherwise 'rattle' do not launch. Without all other packages 'rattle' starts very well. But what will be better, the inclusion or not of the 'datasets', 'grDevices', 'graphics', 'stats' and 'methods' packages in this launcher code? I do not understand if they are needed for proper functioning of the 'rattle'. Regards, Iurie 2011/4/16 Prof Brian Ripley This is a result of bugs in rattle. The first bug is that you are explicitly asked on its help page not to use installed.packages() in that way. Second, packages should be able to be loaded in a session with just base loaded, so rattle's startup code should have utils::installed.packages(). (In this case it is invoked from rattle(), AFAICS, hence not invoked in the loading tests in R CMD check.) However, your startup code is wrong: from ?options defaultPackages: the packages that are attached by default when R starts up. Initially set from value of the environment variable R_DEFAULT_PACKAGES, or if that is unset to c(datasets, utils, grDevices, graphics, stats, methods). (Set R_DEFAULT_PACKAGES to NULL or a comma-separated list of package names.) ^^^ And by default, R_DEFAULT_PACKAGES is unset. Try sh -c 'R_DEFAULT_PACKAGES=datasets,utils,grDevices,graphics,stats,rattle R $@' (You may or may not need 'methods' as well.)

So now I was able to run the library(rattle) then, using: rattle() I have following error message, it wants to install GTK+, what I do, restart R but then it does not work and I have following error message: Error in inDL(x, as.logical(local), as.logical(now), ...) : unable to load shared library 'C:/Programme/R/R-2.10.0/library/RGtk2/libs/RGtk2.dll': LoadLibrary failure: Die angegebene Prozedur wurde nicht gefunden.

Re: [R] Problem with RGtk2 Rattle
The tooltip error is a known issue - old versions of GTK (or perhaps RGtk2)
did not have the function I am now using to install tooltips. You need to
follow Felix's advice and install a new version of GTK (nothing to do with
R), then install R - the order used to be important.
I would suggest starting over again - unistall everything and then follow
the instructions precisely.
I don't think the SVG is an issue.
As a temporary fix, try:
library(rattle)
crv$load.tooltips - FALSE
rattle()

Graham

I feel with the great advice I am getting from Felix Graham, that I am
finally making progress I feel that finally I have identified the REAL
PROBLEM. Of cause I am unsure how I will solve it but that is another
story.
The trace follows after following Grahams latest advice
Error in normalizePath(path) :

Um, it sounds as if you are trying to install glade-3.4.3-win32.zip

GTK+/Glade is a system library to be installed into Windows.
You should download the .exe (not the .zip)

Re: [R] RODBC crashes connecting to Teradata

Most likely a broken driver. It seems that several do not support
GetInfo correctly: isql does not use it by default. Debugging will show
you where the error actually was.
I came across the same problem recently and could not find any
discussion on the r-sig-db list solving this. Here's my solution.
I have a similar setup - Teradata ODBC driver on amd64 GNU/Linux
(Debian), using the RODBC package, and getting a segfault on
odbcConnect.
odbcConnect calls odbcDriverConnect which in turn .Call's
C_RODBCDriverConnect, which actually succeeds. Then there is a .Call
to C_RODBCGetInfo which results in the segfault.
I suspect underneath the Teradata driver is crashing on querying a
table that does not exists or that you may not have access to (for me
the default odbc GetInfo seems to try to access the table DBC.Table,
but our setup does not have that available, with DBC.TableX being used
instead!)
I dropped the GetInfo call from odbcDriverConnect and all is well,
until I query a table that does not exist, and once again the Teradata
driver crashes (also crashes in isql when typing help or querying a
table that does not exist).

Graham

[R] [R-pkgs] pmml 1.2.0 (predictive modelling markup language)
Version 1.2.0 of pmml has been released and is available from CRAN. The pmml package (http://rattle.togaware.com/pmml.html) is part of the Rattle data mining suite http://rattle.togaware.com. It generates representations of analytic models built in R using the open standard predictive modelling markup language (http://www.dmg.org/). PMML represents analytic models in an application independent way so that models developed in R can be loaded into other applications. Supported models include: arules, hclust, kmeans, ksvm, lm (and glm), nnet, rpart, and rsf. PMML consumers include Information Builders' C code generator (for deployment of R generated models within Web Focus on all of their supported platforms), Zementis' scoring engine or cloud computing application (ADAPA), Teradata's Warehouse Miner and IBM's DB2. A key update is the incorporation of a framework for dealing with data transformations. This is ongoing work. The pmml package is regularly updated and intermediate releases (between the more stable CRAN releases) are always available using: install.packages(pmml, repos=http://rattle.togaware.com;) Comments, bugs, suggestions are always welcome.

[R] [R-pkgs] Rattle 2.4.0 (Data Mining GUI using R)
Version 2.4.0 of Rattle has been released to CRAN. The rattle package (http://rattle.togaware.com) is a multi platform (GNU/Linux, Mac/OSX, MS/Windows) GTK based GUI for data mining (for exploring data and building descriptive and predictive models). It has undergone a lot of development over the past year. A companion book introducing data mining using Rattle is under development, with a draft available for review at: http://datamining.togaware.com/survivor/index.html. Rattle is regularly updated and intermediate releases (between the more stable CRAN releases) are always available using: install.packages(rattle, repos=http://rattle.togaware.com;) Rattle builds upon many R packages. Full installation instructions are provided at: http://datamining.togaware.com/survivor/Installing_Rattle.html Recent updates include: * Many bug fixes, GUI simplifications, improved colour usage (through the vcd package). * Streamlined handling of datasets (combined the Data and Select tabs), including support for CSV, ARFF, and ODBC data sources. * Addition of Test and Transforms tabs, with scripting support for transforms, both in building a model and in scoring. * Experimental support for automatic report generation using odfWeave (and hence, generation of OpenOffice documents). * Supported modelling includes: - Cluster (kmeans, hclust) - Association Rules (arules) - Linear Models (lm, glm) - Trees (rpart, party) - Neural Nets (nnet) - Support Vector Machines (ksvm) - Boosting (ada) - Random Forests (randomForest) * Supported data exploration tools include GGobi and PlayWith (latticist). * ROC curves, CostCurves, and many standard plots are supported. * Export to PMML is supported for many models, allowing R (and hence Rattle) models to be readily exported to other tools (see http://www.zementis.com) * The Business Intelligence vendor, Information Builders (http://ibi.com), will soon release RStat (sharing Rattle's open source code base) for data mining within WebFocus. Models built using RStat are deployable via PMML on all WebFocus hardware platforms (over 30 hardware and operating system platforms). A complete change log is available from http://code.google.com/p/rattle/source/list Comments, bugs, suggestions are always welcome.

[R] Does file.info man page describe ctime corrrectly?
(R 2.8.0 on Debian GNU/Linux sid) ?file.info contains: mtime, ctime, atime: integer of class 'POSIXct': file modification, creation and last access times. This implies that ctime is file [...] creation [...] time Has R implemented ctime differently to Unix? I understand, on Linux at least, that ctime is the last change time (not the creation time). See man ls which says: -c [...] ctime (time of last modification of file status information) [...] However, testing seems to indicate file.info is returning the change time, not creation time (I'm not sure we can actually determine creation time of a file on Linux).

Received Fri 10 Oct 2008 5:21am +1100 from Greg Snow: I am not involved in the RExcel project. I have just had some discussions with the people that are, so you should contact them for specific questions. I believe that this currently only works on windows, there was some mention of possibly expanding it to OpenOffice so that it would be cross platform, but I have no idea if that has made it past the good idea stage. I saw it demo'd on OpenOffice calc at UseR! 2008 as I recall --- it looked good. It was not yet released. For quick GUIs specialised for specific tasks, I use the Glade tool to graphically build the GUI - very quick and easy. Glade saves the GUI specs into XML. The RGtk2 package in R can read that XML file and display the GUI. The callbacks (i.e., the functionality called upon when you click a GUI button) are simply R functions. (Rattle is implemented this way.)

Re: [R] playwith package does not work on Ubuntu?
Received Mon 30 Jun 2008 8:58pm +1000 from Karl Ove Hufthammer: Ingo Michaelis: I try to use the interactive plot package playwith on my machine (Ubuntu 8.04 64 bit / Gnome) using R version 2.7.1. My problem is that the widgets are not shown. I tried to plot the examples from the documentation, but it does not work anyway. FWIW, I have the same problem on a Fedora 8 system running KDE and the latest R Patched. Similarly Debian. The author is aware of the problem on GNU/Linux. Apparently works well on MS/Windows :-( The author is on holidays at the moment and has said he'll have a look at this once he returns. (Of course, source is available so anyone is welcome to have a go at fixing it.) It looks like a very nice package, once it works.
