Is it possible to generate graphical output (to a file) when the DISPLAY environment variable is not set? Here's the problem: $ unset DISPLAY $ R > png("foo.png") Error in X11(paste("png::", filename, sep = ""), width, height, pointsize, : unable to start device PNG In addition: Warning message: unable to open connection to X11

I am having problems with trying to run R from a crontab job. I have a c-shell file that calls the R script. I get an error concerning the X11 display (see below). I have included the c-shell file and the output from the crontab job. It appears that my DISPLAY environmental variable is not set. Is that necessary, even when the output of the plot command is to a png file? Can someone tell me how to

Hi, I was wondering if someone in the mailing list has any insight into this segfault error that I consistently find when running a script containing heatmap() in R 2.8.1 and 2.8.0 on a Linux 64-bit machine. Some points: 1. This occurs when running heatmap(). 2. Interestingly, if I source() the script or copy and paste the script in its entirety, this error occurs. However, if I run the

Hi, Is there a way to turn off the automatic inclusion of "./" at the beginning of a path specified in an \SweaveInput{} instruction? I'd like to create some reusable "template modules" of Sweave code and put them in a standard directory like /Resources/Affymetrix Then the corresponding file that uses one of these would include a command like

There is a serious problem with the makewhatis cronjob under Redhat Linux 4.0/3.0.3. You can use it to overwrite any file on the system. Redhat is aware of the problem, and said they would have some kind of fix by next week which should be plenty of time before this bug is exploitable again. #!/bin/sh # # blowitawaysam # # makewhatis is a shellscript that stores a tmp copy of the whatis #

I am not understanding something about generating PNG plots. I have tried several ways to obtain something other than a transparent background, but nothing I've done seems to change the background. For example: dev.print(png, width=800, height=600, bg='red', filename='example.png') which I thought would give a red background, simply gives the same transparent background I

Dear R-helpers, I'm having trouble compiling R packages from source on Win2K. I installed R 1.7.1beta [1] on my win2k machine [2], downloaded the fields package as source [3] and tried but failed to install the package [4]. I get the same problem with other packages, so it doesn't appear to be limited to fields. Installation of precompiled packages seems to work fine. I've been

During installation of a package, Makevars/Makefile in src/ is processed. I've always considered the purpose of this for compiling native code. Is that it's solely purpose, or is it alright to use it also for non-code compilation purposes, e.g. building inst/ subdirectories on the fly? If not, are there other means to create non-static inst/ subdirectories during installation? The
