No, haven't seen this so far. But it quite looks like what I'm looking
for, so thanks a lot :-)

Hi again,
Sorry for bothering you, but have you seen this?

or this one

Maybe something for you?

Hi Dennis,
Possibly, but I am not sure. X11 is, as you know, not a library,
but a
server. As such, it has built-in security.
It is possible that you can make an X-server of a server machine to
accept connections from a script run by a webserver (and thus not
by a
user who gained access and has all the PAM credentials due to a user
log-in), but for me it seems like way too much hard work to get it
going (and it would also probably create an issue with security on
the
way, I don't know.)
Anyway, I would go for an intermediate temp-file solution. Maybe EPS
-> png conversion could work, and give good results (if PDF -> PNG
conversion does not)?
Good luck!

Hi Fredrik,
well I'm connecting via SSH onto the machine. Lateron the R
scripts shall be
executed via some Ruby scripts. The pdf export is working
properly, but I
think it would be very ugly to first create a pdf file and then
convert it
to my needed png (or any other pure image format). Is there no way
to
manually connect to X11 even in my use case?

Hi Dennis,
Are you working from a remote client, i.e. not logged into the
machine
locally (in X)? If so, the png and jpg devices seem to need to be
able
to connect to X.

Try using the pdf device instead.

Hi there,
after several problems with installing R on a Debian server It now
finally
works at least roughly. With roughly I mean that the 'core'
function do
work
properly, but I'm still having problems with the image export.
When I try
to
call
png(filename="my_file.png", width=800, height=300, pointsize=12,
bg =
"white")
I just get the error message "X11 is not available". But I don't
know
what
packages (or symlinks???) could still be missing.
I've installed R using the latest 2.8.0 version from the server
which I
could compile (after solving quite some different problems)
normally.
I hope anyone can help me out, best wishes,
Dennis Schmidt
