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, sep = ""), width, height, pointsize, : unable to start device PNG In addition: Warning message: unable to open connection to X11 display '' Execution halted When X11 is working everything works fine. Is there a way to make this work without X11? Or, how would I simulate an X11 environment (including the correct DISPLAY variable) on a cluster node? I appreciate any comments or suggestions.
