this is not a problem with R but a request for related advice.

i am trying to run a lengthy batch job from my home.

the OS is ...
Linux jedi.bwh.harvard.edu 2.4.22-openmosix1smp #1 SMP Fri Sep 5 01:05:37 CEST 2003 i686 athlon i386 GNU/Linux

i start the job and put it in the background. while i am connected, all is well. eventually my ISP shuts down the connection if i do not do any input. then:

Boxplots of G intensitiesError in X11(paste("png::", filename, sep = ""), width, height, pointsize, :   unable to start device PNG
Calls: doPlot -> qcBeadLevel -> png
In addition: Warning message:
In png(filename, width = 640, height = 480) :   unable to open connection to X11 display '' Execution halted

is it possible to have X11() succeed when there is no real display to connect to?
