Hi Tony, I looked over the files and I am puzzled why the difference in font sizes. Unfortunately my knowledge about X window configurations is pretty scant. (You mention in the shell script comments that you run the job as root, so I wonder if that makes any difference to X..I doubt it). I recall some threads on X devices and font sizes in the R-help archives, so you may wish to consult there. You also suggested an XFree86 list, and I think that would be a good idea to post.
But as a potential workaround thru R, perhaps the cex settings (see ?par), like cex, cex.axis, cex.lab, cex.main, and cex.sub could help you adjust the font-sizes down to what you would like. > > Adjusting the pointsize argument in png might help. > > I've played with this a little. Any specific value you suggest? I use pointsize = 10 in my set-up for png() with Xvfb, which is somewhat different from the default (12). It is hard to judge if that will reduce your size enough.
