This isn't exactly the same as your problem, but I came across access to X11 problems when running R over CGI. I got round it by installing Xvfb (X Virtual Frame Buffer) on the server. Mick

I am trying to run R on a remote machine, part of the model run I am attempting writes an external file output as a png (about 48 iterations per model run). I am running R 1.9.1 on SuSe9.0, and am accessing this via ssh from a Debian machine. Initially I used the command ssh -X IP.address and whilst I was able to run the model successfully the model run was extremely slow (which I could not understand as the output was being written to the remote machine), but tried to log in again, this time without the X windows facility and found that I couldn't run the model: 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 display`' Could somebody please advise a way around this?
