[R-SIG-Mac] [R] Mac OS X R.app has trouble rendering certain fonts.

[sgruber at berkeley.edu]

I  recently experienced  the same problem.  Text  that was missing from
plots in the Quartz window appeared on plots that were sent directly to a 
pdf file. Interestingly,  text that was printed using the expression
function did appear in the quartz window, for example,
ylab=expression(hat(psi))

As Marc wrote, the problem was resolved when I used Fontbook to resolve
duplicated fonts, which for me were Arial and Helvetica stored at both the
System and User level.   Hopefully this will work for you as well.

really know where to check if I have the proper true type fonts
available on my computer or if it is a problem within R itself. This
doesn't appear to be a problem with the functioning of R itself, just an
inability for it to render certain fonts on graphical displays. I just
want to fix it now before I use it in a major project that
requires the rendering of fonts onto the screen for presentations
etc...
