Hi all,
I've run into the following problem with Sweave: I frequently run Sweave
from a xterm console within an X session owned by a different user, i.e.
my colleague is logged in on this computer and I do "su" with my
username and start R and Sweave afterwards. Now, when Sweave comes to a
figure chunk, it sees that there is an X server running and tries to
show whatever I plot in that chunk on the screen, additionally to
writing a pdf file. The problem is that I am not logged into the X
session myself, and the script fails with a message saying someting like
"could not open device X11" (I have German messages, so I do not know
what the exact phrase would be in English). When I log in with putty,
where there is no X11 at all, everything works fine. Is there a way to
prevent Sweave from failing in the former case? Would this even account
as a bug? I think it would be nice if the script just kept on running
without plotting on the screen if opening X11 fails, just like it does
when no X11 is available at all.
Best regards,
Andreas
