I wasn't aware that it was possible to use postscript in the same fashion
as png, eg:
png(file,width=x,height=y,)
image(map)
text(text)
title(title)
box()
dev.off()
As there are a large number of iterations png has been working nicely
(when not working remotely!), especially as it has proven easy to convery
into gifs and then into movie gifs. Could anyone suggest an alternative
approach in this case?
Start an Xvfb (X11 virtual frame buffer) server in your remote ssh
session. R will then use that as an X11 device to produce the PNG
output. If you are running in a hostile network environment, consider
using authentication and/or switching off network access to the Xvfb
session - see the man pages for Xvfb. Xvfb is installed by default on
most recent Linux distributions - if not, there should be an installable
package available for it for your flavour of Linux.
