Michael, To create (most) chart types in batch mode or on a headless terminal, you need to set up a 'virtual' X11 server.
This has become easier using the additional XFree86 'virtual framebuffer server'. The package is called Xfvb, and your Linux distro will most likely have it. You can also get it for Solaris and the other commercial unices. With a bit of luck and google-ing, you should find some examples and howtos. People who know more about security than I do advise against modifying xhost settings at almost all costs. Hth, Dirk -- Don't drink and derive. Alcohol and analysis don't mix. ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
