Hello,
I am running some commands in batch on a server that I SSH into; some of
the commands call jpeg(). If I continue to stay signed on (with my
xwindows working on my machine) then the jpeg() command works (with a
single caveat, below). If I leave it and sign off (with a nohup command
in front of my BATCH) then jpeg gives me an error like this:
Error in X11(paste("jpeg::", quality, ":", filename, sep = ""), width, :
unable to start device JPEG
In addition: Warning message:
could not open JPEG file xyz.jpeg
I don't have this problem with pdf(); but the images I want to draw are
really massive in terms of the number of points/images so they take
forever to open in adobe (as well as being HUGE) so I'd like them in
jpeg. Can I get around this somehow? I saw other people posted similar
problems, but saw no solutions.
R-2.6.0, GNU/Linux
Thanks,
Elizabeth
My caveat from above about the jpeg working as long as I'm signed on:
one time I got the mysterious error:
>
jpeg("~/batch5Effect/ProbPbsets_summaryHeatmaps%03d.jpeg",height=1200,width=800)
Error in jpeg("~/batch5Effect/ProbPbsets_summaryHeatmaps%03d.jpeg",
height = 1200, :
X11 fatal IO error: please save work and shut down R
Even though it had just correctly done this same basic command a few
lines back. I redid it (without changing anything that I was aware of)
and it worked fine. So I don't think it's related.
