Re: [R] cbind question, please
Hello, I am not sure what you mean by a matrix. If you want to have a matrix, use the function matrix, (matrix(c(dog,cat,tree),3)) but I have the feeling you really want a data frame as you are talking about variables. In that case simply use mydataframe - data.frame(dog,cat,tree) If you are not sure what you want, please read the intro to R pdf which is included in your installed R library.

Re: [R-es] Diferencias entre la version de 32 y 64 bits
Hola Sergio, En principio las diferencias entre 32 y 64 bits están relacionadas con cuánta RAM puede gestionar R. Esto efectivamente puede afectar a tu problema por el nivel de profundidad que el algoritmo simplex utilice hasta encontrar la solución y eso está asociado con la RAM que puede gestionarse. De todas formas prueba, en tu máquina de 32 bits, a modificar los parámetros de control donde supongo que podrás indicar el número máximo de iteraciones o incluso la precisión con la que simplex ya considere que ha convergido a una solución. Estos parámetros suelen estar en una función auxiliar de control. Saludos, Carlos.

Re: [R] - Obtaining superscripts to affix to means that are not significantly different from each other with R
Hi Joachim,
This function allows the user to set some characters in a string to
superscript or subscript. If sup or sub are set to one or more numbers
corresponding to an index in the string, those letters will be placed
appropriately. I can't properly test this as there is some problem
with X11 fonts that has appeared with the upgrade to R 3.2.0 and the
cex argument seems to have no effect.
supsubtext-function(x,y,label,sup=NA,sub=NA,cex=1,sscex=0.8,xadj=0,...) {
nlabchar-nchar(label)
yadj-rep(0.5,nlabchar)
if(!is.na(sup)) yadj[sup]-0
if(!is.na(sub)) yadj[sub]-1
labbits-strsplit(label,)[[1]]
currentx-x
for(labchar in 1:nlabchar) {
text(x,y,labbits[labchar],adj=c(xadj,yadj[labchar]),
cex=ifelse(yadj[labchar]!=0.5,sscex,cex),...)

}

[R-es] Diferencias entre la version de 32 y 64 bits
Buenos días, He hecho un desarrollo en mi máquina (de 64 bits) y funciona correctamente. Se trata de un problema de programación lineal (usando lpSolve y lpSolveAPI). El problema viene al ejecutar un caso concreto que en la máquina del usuario (de 32 bits) nos da que no hay solución factible para ese problema, pero en mi máquina de 64 sí que nos devuelve una solución. ¿Hay alguna forma (limitar decimales, por ejemplo) de solucionar esto? He probado con las versiones de R 3.1.3 y 3.2 Muchas gracias. Un saludo. ___ R-help-es mailing list R-help-es@r-project.org https://stat.ethz.ch/mailman/listinfo/r-help-es
Re: [R] cbind question, please
I am amazed at the number of rather obtuse misunderstandings of the actual nature of Erin's question. The suggestion that Erin should read the intro to R made me smile. Erin is a long time and highly sophisticated user of R; she has no need to read the intro. The person who made that suggestion should have read her question more thoughtfully. Also I liked Steve Taylor's and Marc Swartz's nifty solutions that use sapply(); much sexier than my rather kludgy effort using do.call(). Berwin Turlach's combination of do.call() and sapply() is pretty sexy too. cheers, Rolf Turner -- Rolf Turner Technical Editor ANZJS Department of Statistics University of Auckland Phone: +64-9-373-7599 ext. 88276 Home phone: +64-9-480-4619 __ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
[R] Error increasing font size in R 3.2.0
I wanted to increase the size of the font in R, but when I do, I get the error message below. I've searched on Google, and the only thing I saw is about changing the version of X11. I'm running the current version of X11, and running OS X Yosemite 10.10.3. I'm using a Mac Desktop, 3.2 Ghz processor. Any thoughts on how I can fix this? Because I have 21.5 inch monitor, the default size of 8 is a little small for my liking. 2015-04-23 20:45:07.429 R[4458:2481342] Layout still needs update after calling -[NSScrollView layout]. NSScrollView or one of its superclasses may have overridden -layout without calling super. Or, something may have dirtied layout in the middle of updating it. Both are programming errors in Cocoa Autolayout. The former is pretty likely to arise if some pre-Cocoa Autolayout class had a method called layout, but it should be fixed.

A good way to spot these is to (a) come up with a _minimal_ reproducible script test.R that takes just a few seconds to run and that tickles, at least some times, the segfault (b) make sure that your package is compiled without optimizations and with debugging symbols, e.g., in ~/.R/Makevars add the lines CFLAGS=-ggdb -O0 CXXFLAGS=-ggdb -O0 (c) run the code under 'valgrind' R -d valgrind -f test.r Look especially for 'invalid read' or 'invalid write' messages, and isolate _your_ code in the callback that the message produces.

Re: [R] Possible bug in rlm
Have just checked with R 3.2.0 and MASS 7.3-40 and there still appears to
be a problem/strangeness at around k=2.5
On 23 April 2015 at 14:09, Francis Bursa francis.bu...@quantics.co.uk
wrote:
Dear all,
I believe I have found a bug in rlm in the MASS package. Specifically, the
scale estimate can be wrong when there are no outliers. The following code
snippet is an example:
dose - c(0,1,2,0,1,2)
response - c(0.659,1.633,3.621,1.803,3.093,4.424)
line - c(1,1,1,2,2,2)
k2 - seq(1.5,5,by=0.01)
repNA - rep(NA,length(k2))
scale - repNA
niter - repNA
for (i in 1:length(k2)){
rlm.fit - rlm(response~dose+factor(line), psi=psi.huber,k=1.345,
scale.est=proposal 2,k2=k2[i])
scale[i] - rlm.fit$s
niter[i] - length(rlm.fit$conv)
}
plot(k2,scale,type=b,col=niter)
For this dataset there are no outliers, so I would expect the scale to be
a smooth function of k2 once k2 is reasonably large, certainly for k2 2.
However, there is a funny jump in the scale estimate around k2 = 2.4, just
at the point where the number of iterations to convergence falls from 3 to
1.
Looking at the source code, it appears that on each iteration, the scale
is updated, then the parameters, and then a check for convergence is
carried out just for the parameters, not the scale. So I would guess that
in the range around k2=2.5 convergence is being reached when in fact the
scale estimate hasn't converged.
I am using MASS version 7.3-33 and R version 3.1.0 on Windows.
I am not sure how common this issue is but there does not seem to be
anything special about my dataset so it could be quite generic. Am I right
that this is a bug?
Many thanks,
Francis Bursa

Hi R-help,
I've looked at google, the Rscript documentation and the Rscript --help
output and haven't found much on this. So, here's my question:
I have a rather long script that runs on various input datasets. It is
quite convenient to run the script from the Terminal command line with
Rscript scriptname.R
However, some datasets will cause errors. These are non-essential
errors --
just some datasets don't have certain columns so certain parts of the
overall analysis don't produce figures etc. Yes, I could go through
the
whole script and insert try() statements, etc. But I'm lazy.
So, is there a way to run Rscript or something similar, and just have
it
ignore all errors (i.e., keep running through the script)? I.e., just
like
what happens if you just copy-paste the whole script into the R window
--
errors happen and are noted but the rest of the script keeps running.
Thanks very much for any help!!
Cheers!
Nick
This is a really, really simple life-hack of mine after failed past
attemps to solve this
issue
:
Option
1
: Write an if(foreseen error){empty} so if _that_ happens, the code just
ignores it.
Option 2: Try to run same code for the different initial values in
different windows, so if one stops, another one keeps running.
I am interested in finding a real solution
(like the one proposed above by Mr. Newmiller)
, so I am looking forward to some more expert's say.
Best regards.

Re: [R] cbind question, please
You could do something tricky like do.call(cbind, lapply(big.char, as.name)) dog cat tree [1,] 1 25 [2,] 2 36 [3,] 3 47 but you are usually better off creating these things as part of a list and passing that to do.call(cbind, list). There is a slight danger of using do.call with cbind. If your list has a component with the unlikely name 'deparse.level', then that will be taken as cbind's deparse.level argument, not as a column of the matrix to be made.

[R] obtaining the sum of lagged variables
Hi everybody, I am trying to replicate the formula shown in the attachment. I want to estimate tau using a macroeconomic variable X at month t using k lags of the variable X. My code so far looks as follows: psi - fn(...) k - 1:K ltau - m + theta*sum(psi*X[t-k]) Unfortunately, if I run the code as shown the result I get is NA but I want to obtain a list of ltaus at month t. ltau - m + theta*sum(psi*X[t-k]) ltau [1] NA Hence I defined t and ran X[t-k] and get following results. That is, X[t-k] provides every third element in my data table three times instead of calculating the sum of the lagged observations multiplied with psi t-1:15 t [1] 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 X[t-k] [1] -0.25 -0.25 -0.25 0.50 0.50 0.50 -0.44 -0.44 -0.44 0.15 0.15 0.15 How do I get the list of taus at month t based on the sum of lagged observations as shown in the attachment?

[R] Interactive maps
Hello, all: I am new here, and have a challenge to present some graphical data to the user in a convenient way. The challenge is to present a map to the user which is coloured with the value of a variable. Say for example, temperature. This is a preexisting graph that I can generate in any format, including svg. I don't have to produce it using R. When the user clicks anywhere in the map, the coordinates (longitude and latitude) have to be passed to R so that this, R, can look for the values of other variables in that location and make another graph with them. Does anyubody know how could I accomplish this?. Thanks in advance.

Re: [R-es] Codificación UTF-8 en un Mc
Pues entonces no sé qué decir, porque no uso Mac y desconozco si el editor de texto que trae permite hacer algo parecido a lo que hace RStudio. Por si acaso es factible para ti, la operación inversa también la puedes hacer desde RStudio (que supongo tú sí lo tienes instalado): File/Save with Encoding. Si lo tienes que hacer rutinariamente seguramente puedas automatizarlo con un script sencillo combinando las funciones readLines, iconv, writeLines. Saludos, E. *Emilio L.

Re: [R] run Rscript and ignore errors?
Hi,
Thanks so much for the hints, I think I've cracked it! The key is to
create a dummy function, continue_on_error which gets run instead of
stop when an error occurs, then reference it
with options(error=continue_on_error). Here's an example:
==
continue_on_error - function()
{
print(NOTE: THERE WAS AN ERROR HERE. We are continuing because we have set
'options(error=continue_on_error())')
}
testfunc - function(a,b)
{
print(a+b)
}
# This is the key option
options(error=continue_on_error)
print(1)
print(2)
# This should work
testfunc(a=10, b=10)
print(3)
# This should produce an error and stop the Rscript run normally
testfunc(a=1)
print(4)
print(5)
==
Running this via Rscript completes:
Rscript continue_on_error.R
[1] 1
[1] 2
[1] 20
[1] 3
Error in print(a + b) : argument b is missing, with no default
Calls: testfunc - print
[1] NOTE: THERE WAS AN ERROR HERE. We are continuing because we have set
'options(error=continue_on_error())'
[1] 4
[1] 5
If you comment out the options() line you get:
Rscript continue_on_error.R
[1] 1
[1] 2
[1] 20
[1] 3
Error in print(a + b) : argument b is missing, with no default
Calls: testfunc - print
Execution halted
...which was what was annoying me before.
So, life hack FTW. (Of course, yes, it would be better to write code good
n stuff, but for quick and dirty things this is handy.)
Cheers!

Hi R-help,
I've looked at google, the Rscript documentation and the Rscript --help
output and haven't found much on this. So, here's my question:
I have a rather long script that runs on various input datasets. It is
quite convenient to run the script from the Terminal command line with
Rscript scriptname.R
However, some datasets will cause errors. These are non-essential
errors --
just some datasets don't have certain columns so certain parts of the
overall analysis don't produce figures etc. Yes, I could go through
the
whole script and insert try() statements, etc. But I'm lazy.
So, is there a way to run Rscript or something similar, and just have
it
ignore all errors (i.e., keep running through the script)? I.e., just
like
what happens if you just copy-paste the whole script into the R window
--
errors happen and are noted but the rest of the script keeps running.
Thanks very much for any help!!
Cheers!
Nick
This is a really, really simple life-hack of mine after failed past
attemps to solve this
issue
:
Option
1
: Write an if(foreseen error){empty} so if _that_ happens, the code just
ignores it.
Option 2: Try to run same code for the different initial values in
different windows, so if one stops, another one keeps running.
I am interested in finding a real solution
(like the one proposed above by Mr. Newmiller)
, so I am looking forward to some more expert's say.
Best regards.
Jue

[R] JPEG command not responding to size options
R 3.2.0 OS X Colleagues I have a script that has been unchanged for years but I just noticed a difference in the output. A minimal example is: jpeg(file=xxx.jpeg, width=4, height=2, unit=in, pointsize=12, bg=white, res=150, quality=100) plot(1) graphics.off() system(open xxx.jpeg) ## works in OS X -- use 'start' instead of 'open' in Windows In the past (probably more than several months ago, although I can’t identify when the change occurred), this yielded a graphic that appears to be the intended size (4 x 2). I assess this based on the size on the screen and the size when I drag the file to a Word document. With R 3.2.0 (and 3.1.3), the image is appreciably larger, i.e., the width and height options appear to be ignored. OS X’s Preview application includes an inspector that provided information about the images. In the earlier incarnations, Inspector reported that the image has 150 pixels / inch. With 3.2.0, it shows 72 pixels / inch. I think that the problem is as follows — the image is created with the correct number of pixels — but the info as to pixels / inch is not being handled correctly. I can confirm this by replacing res=150 with res=72 The resulting image is the intended size. Is this a bug? The workaround appears to be restoring res=72 but that does not seem to be an ideal solution.

Hello!
I have a cbind type question, please: Suppose I have the following:
dog - 1:3
cat - 2:4
tree - 5:7
and a character vector
big.char - c(dog,cat,tree)
I want to end up with a matrix that is a cbind of dog, cat, and tree.
This is a toy example. There will be a bunch of variables.
I experimented with do.call, but all I got was
1
2
3
Any suggestions would be much appreciated. I still think that do.call
might be the key, but I'm not sure.
R Version 3-1.3, Windows 7.

Hi Erin,
One approach could be:
sapply(big.char, get, mode = integer)
dog cat tree
[1,] 1 25
[2,] 2 36
[3,] 3 47
or
sapply(big.char, get, mode = numeric)
dog cat tree
[1,] 1 25
[2,] 2 36
[3,] 3 47
Note that I used the ‘mode' argument to get(). You used ‘cat’ as the name of
one of the objects and of course, there is an R function cat(). By default for
get(), mode = “any”, which would otherwise result in:
sapply(big.char, get)
$dog
[1] 1 2 3
$cat
function (..., file = , sep = , fill = FALSE, labels = NULL,
append = FALSE)
{
if (is.character(file))
if (file == )
file - stdout()
else if (substring(file, 1L, 1L) == |) {
file - pipe(substring(file, 2L), w)
on.exit(close(file))
}
else {
file - file(file, ifelse(append, a, w))
on.exit(close(file))
}
.Internal(cat(list(...), file, sep, fill, labels, append))
}
bytecode: 0x7fe942d78f78
environment: namespace:base
$tree
[1] 5 6 7
In the above, the cat() function body is returned, instead of the vector cat.
So just need to be cautious.
An alternative approach, depending upon where your vectors are stored, might be:
sapply(big.char, get, pos = 1)
dog cat tree
[1,] 1 25
[2,] 2 36
[3,] 3 47
which specifies which environment to search for the named objects and the cat()
function is not returned since it is in namespace:base.
See ?get

Re: [R] cbind question, please
This works for me... get0 = function(x) get(x,pos=1) sapply(big.char, get0) The extra step seems necessary because without it, get() gets base::cat() instead of cat. cheers, Steve -Original Message- From: R-help [mailto:r-help-boun...@r-project.org] On Behalf Of Erin Hodgess Sent: Friday, 24 April 2015 10:41a To: R help Subject: [R] cbind question, please Hello!

Re: [R] cbind question, please
These are great! Thank you!

There is a slight danger of using do.call with cbind. If your list has a component with the unlikely name 'deparse.level', then that will be taken as cbind's deparse.level argument, not as a column of the matrix to be made.
