R help - Jul 2004 - jpeg() on UNIX

Dear R users,

I am currently having difficulty migrating a web application from XP to a 
SGI UNIX since when I run R in the background (i.e. in a process started 
from the web server) the graphics device jpeg() requires, but cannot 
connect to, X11. I could go via bitmap() and PS but wondered if there was 
another way forward. I am currently running R version 1.6.2. Ideally, I 
would like may R source to be compatible with Windows.

Any help or suggestions would be more than welcome!

yours

The FAQ suggests that running Xvfb, which provides an X server with no
display, may work.  I understand that the CRAN people do this.
