Hello! When I am trying to produce plot with text with pointsize 30 or greater R sets up a default pointsize of 12 on plot. I need to set up a large pointsize to make large jpeg or png files (with good resolution). I can write text on plot with pointsizes 18,20,22, but i cant write text with pointsizes 25,26 and greater and i can not understand - why? Is there are any restrictions in R? Or what? I am using R 1.7.0 on Win2k Thanx.
pointsize - what is wrong?

You have the sources: look at src/gnuwin32/devga.c, line 2217. You can change that as you please and recompile R. *However* that is the base font size, and R uses graphics parameter cex to scale the text thereafter. There are limits of [2, 100] points for the scaled font size. The default is 12 point, on a 7" square window. 24 point might be appropriate to a 14" or 1000 pixel png/jpeg. That's pretty high resolution, and if that is not enough, I would question why you are using a bitmap format anyway, and if you absolutely needed to I would suggest you used some other tools to rasterize (as R's bitmap() function does).

Perhaps you should say that first, *and* that you are using a png() device (if you are).
