[R] Runnning R remotely

[michael watson (IAH-C)]

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.

	Hi,
	
	I was wondering if anyone might be able to help. 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?
	
	Thanks in advance,
	Laura
