similar to: generating graphical output when DISPLAY is not set?

I had the same problem with trying to run R from a cgi script on the web. The only way I got it to work was to set the DISPLAY variable to the server itself. That way the cgi script had permission to do that because it was using the server web user account on the server. So I added the following to the cgi script: setenv DISPLAY servername:0 This also works for crontab jobs that don't have a

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

Hi, I got this error while using png() function in RedHat 9.0.

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

On my current home system, I am getting undesirable output from graphical devices such as png() and pdf(). The graphical output is blurry. I haven't experienced the problem on other systems. As you will see from the attached text file (more information on this file below), the problem does not occur when type='Xlib' is forced. The blurriness is more severe with bitmap output (yes, I am

Hi All, I am running R 2.6.0 on an Ubuntu 8.04 with Rserve on a machine. I send R commands from a Windows computer to the R machine and a few commands require the creation of plots on png devices. I often get the following error: Error in X11(paste("png::", filename, sep = ""), width, height, pointsize, : unable to start device PNG I've solved this error at times by

I cannot generate png files running R2.2.1 on a SunOS 5.9 machine. See below. I did a search on this problem and people who have virtually the same error have solved the problem by installing or updating libpng . We downloaded libpng from Sun but still the problem remains. Does a path within R need to be set to this file or does the problem indicate that libpng was not installed properly? I

Hi there, I want to run an R script on a cluster with qsub. Obviously I don't want to display any X window, but I want use png() or something else to write out images. Unfortunately I get the following error message: > png(filename = " ALL.png", width = 480, height = 480, pointsize = 12, bg = "white", res = NA) Error in X11(paste("png::", filename,

Hi! When inserting R plots into a document using odfWeave, I fought for a while to get Lattice plots use the same text size as base plots. I eventually discovered that specifying a point size via e.g. svg(pointsize=10) has no effect on Lattice plots. One needs to adjust the size manually via: trellis.par.set(fontsize=list(text=10, points=8)) This is also developed for both Lattice and ggplot2 by

Is there any possibility to get high resolution plots in a windows xp system? I tried it with the device function png(filename = "c:/r/highresplot%d.png",pointsize=12, res=900) but when I try to set: width = 480, height = 480 or pointsize = 12, the text is not scaled in the same way as the plots. with regards Knut Krueger http://www.biostatistic.de

Hello, I'm trying to adapt some R code that works on Windows so that it will work on a Linux machine. The command : png("myFile.png", width=600, height=600) fails claiming that it is impossible to establish a connection with X11. (Error messages are in French, so I'm not pasting them here!) I have libpng installed: >rpm -qa libpng* libpng-1.0.12-2

Dear colleagues, Saving a plot with pdf gives a very nice result: pdf("myplot.pdf") par(font=1,family='serif') plot(pressure) dev.off() Doing the very same with other formats (png, jpeg, tiff) gives far worse results. Is there anything to do to make a plot in some other format than pdf look like the pdf? Hardly any journal accepts pdf files for figures, and most do accept png
