There are other ways, but if you have (or can install) libgd and freetype, you may consider using the GDD device - it can produce jpeg, png and gif on unix w/o the need of X11. The nice thing about it is speed (it doesn't use any external process) and that it uses anti-aliasing of both text and lines. It was designed specifically for graphics-on-demand on web servers.

Currenly GDD is not on CRAN (yet), but you can get it from http://www.rosuda.org/R/nightly/
Just make sure that you have libgd and freetype (if you any problems or suggestions, please drop me a line).

There are other methods, too, like the bitmap device, which uses gs (AFAICS), or you can run virtual X11 to satisfy the devices that require X11.

Cheers,
Simon
