Hi All, I am currently using R version 2.8.1 on linux cent os 4.4 (i386) and want to upgrade to version 2.9.1. It seems to me that version-2.9.1 is it not for my OS. Am I right? Regards Utkarsh [[alternative HTML version deleted]]

Hi, With reference to the mail below, I have large datasets, coming from various different sources, which I can read into filebacked big.matrix using library bigmemory. I want to merge them all into one 'big.matrix' object. (Later, I want to run regression using library 'biglm'). I am unsuccessfully trying to do this from quite some time now. Can you please

Hi All, I have vector of length 52, say, x=sample(30,52,replace=T). I want to sort x and split into five *nearly equal groups*. Note that the observations are repeated in x so in case of a tie I want both the observations to fall in same group. This seems a very common task to do, but still I couldn't find an R function to do this. Any help would be highly appreciated. Regards Utkarsh

Dear all, I noticed that the r-base package for Ubuntu 8.04.1 do not have the tcltk support compiled in. Would it be possible to correct this? > echo "capabilities()" | R --no-save | tail -6 [Previously saved workspace restored] > capabilities() jpeg png tcltk X11 aqua http/ftp sockets libxml TRUE TRUE FALSE TRUE FALSE TRUE

I am using the library(bigmemory) to handle large datasets, say 1 GB, and facing following problems. Any hints from anybody can be helpful. _Problem-1: _ I am using "read.big.matrix" function to create a filebacked big matrix of my data and get the following warning: > x = read.big.matrix("/home/utkarsh.s/data.csv",header=T,type="double",shared=T,backingfile

Hi all, I am performing a stepwise regression by running the "step" function on an "lm" object. Now I want to save the intermediate iterations. I know the argument trace=T will print it on the console, but I rather want to assign it to some R object or may be output it in a CSV or text file. Any help will be appreciated. Regards Utkarsh

Hello, I think there is a problem in recent devel builds of R on Windows with various devices from the grDevices package. For example: > capabilities() jpeg png tiff tcltk X11 aqua http/ftp sockets TRUE TRUE TRUE TRUE FALSE FALSE TRUE TRUE libxml fifo cledit iconv NLS profmem cairo TRUE FALSE TRUE TRUE

Hi All, I am currently doing the following to compute summary statistics of aggregated data: a = aggregate(warpbreaks$breaks, warpbreaks[,-1], mean) b = aggregate(warpbreaks$breaks, warpbreaks[,-1], sum) c = aggregate(warpbreaks$breaks, warpbreaks[,-1], length) ans = cbind(a, b[,3], c[,3]) This seems unnecessarily complex to me so I tried > aggregate(warpbreaks$breaks, warpbreaks[,-1],

Hi all, I want to define a function such that one of its argument if passed do one thing and if not passed do the second thing. So basically, I have to check whether the argument is passed or not inside the function. I am trying to use 'exists' function to do this. > f = function(a,b){exists("b")} > f(a=3, b=4) [1] TRUE This is working as expected.

I'm running R 2.11 on Karmic. I'm having difficulty installing quite a few packages with the returned error message of "installation of package "[whatever the packages happens to be]" had non-zero exit status. I know this message sometimes is caused by incorrect or missing java packages and the like. I generally don't have issues with the installation of R or R packages

Dear all, I am having problem on plots in R for some cases. For example: > plot( 1:10 ) > text( 1:10, letters[1:10], cex = 1) works well but : > plot(1:10) > text(1:10, letters[1:10], cex = 0.9) returns : Erreur dans text.default(1:10, letters[1:10], cex = 0.9) : impossible de charger la police X11 -adobe-helvetica-%s-%s-*-*-%d-*-*-*-*-*-*-*, de face 1 et de taille 11 (sorry

Hi all, I'm having trouble getting x11 to work with R. (This is on Debian testing.) I installed r-base and r-base-dev, and then r-cran-cairodevice. I also tried installing the Cairo package within R, which appears to work fine. This what I'm seeing: > capabilities() jpeg png tiff tcltk X11 aqua http/ftp sockets TRUE TRUE TRUE TRUE

Hello, I 've just re-installed R 2.9.0 on ubuntu 9.04. I do not understand why I am unable to use simple device function such as jpeg(), png()... > png() Error in X11(paste("png::", filename, sep = ""), width, height, pointsize, : unable to start device PNG In addition: Warning message: In png() : no png support in this version of R > capabilities() jpeg

I define the following function: (Please don't wonder about the use of this function, this is just a simplified version of my actual function. And please don't spend your time in finding an alternate way of doing the same as the following does not exactly represent my function. I am only interested in a good explanation) > f1 =

Hi, It seems that anti-aliasing in png(type = 'cairo') is not well supported for the point symbols without boarders, e.g. pch = 16. The Cairo package works well, though. You can compare png() with CairoPNG(): png(): http://i.imgur.com/8niB3jX.png CairoPNG(): http://i.imgur.com/FZBJOxm.png f = function(dev, ..., main = '') { dev(...) plot(c(1, 2, 1, 2), c(1, 1, 2, 2),

I apologize if this is too obscure to reproduce, or some idiosyncratic aspects of my system. If I create a plot, e.g., > plot(1:10) I get a graphics device as expected. I then click on the 'zoom' box on my X11 window, so the window expands to occupy the entire screen. The plot is redrawn at the scale of the large window, but is clipped to the 'unzoomed' size. I only

Dear r-developers, I currently face an issue while compiling R from source on a debian wheezy. When running the configure script (particularly with --enable-R-shlib --prefix=/packages/R/3.1.0/) I get a Makefile and the output ...

I just installed R on Redhat Linux at work for the first time and have two questions. 1. I tried to install R to have png and cairo capabilities and was unsuccessful. Before running make, I ran ./configure --with-libpng=yes --with-x=no --with-cairo=yes --with-readline-yes . R installed fine, but when I run R and type capabilities() > capabilities() jpeg png tiff tcltk

I love the new tiff(), jpeg(), and png() in R 2.7.0 but found an issue that I didn't see reported. When specifying 'units = "in"' but forgetting to change the default height and width (so the figure is unintentionally going to be 480 inches by 480 inches) I run into problems. Here's the reproducible example: tiff("a.tiff", units = "in", res = 1200,
