[R] 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).
