X11 helpers,
Howdy. I am trying to create graphs using a program called R (a
statistical program - www.r-project.org) via cron. R uses X11 libraries
to interface with the libpng and libjpeg libraries to generate graphs.
I have been able to create graphs (using cron/R) by first starting Xvfb -
the problem is that my fonts don't look right inside the graphs. Any ideas how I could
solve/troubleshoot the problem?? I run into the graph font problems on
both Solaris and Linux. I start Xvbf with the attached script.
Any help would be appreciated.
Thanks,
Tony
