As far I can remember you have never offered either sessionInfor(),
nor a sample problem in R code, nor an explicit description of what is
being produced, nor a pdf file that can be examined. I have run
demo(plotmath) and it appears not to exercise fonts ot any exceptional
degree .... no theta's, tau's or gamma's. Do you care to exapnd on
your difficulties?

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

I did have some duplicated fonts in my font book. So I resolved the
duplicates but it did not take care of the problem. There are still no
letters or numbers being rendered in quartz. Only in X11. I looked up
the quartzFont() function, to see if it might help, but so far
nothing. Quartz is the graphics engine that renders PDF, so if it
renders in PDF it should render in Quartz and vice versa. But that is
not the case apparently.
I hope that somebody has any additional input as to why this happens.
EDIT:
Okay, it seems that X11 renders the fonts etc...okay
Typing in:
X11()
demo(plotmath)
dev.off()
seemed to render everything including the fonts fine, so I don't
think
any
of my fonts are corrupted.
But is there a way to configure R to set X11 as the default device
for
graphics? Right now, it uses quartz as its default device for
rendering to
the screen. I'm a bit of a newbie here, so could somebody explain
how to
add to my R config file to have the default device be X11?

I noticed this running a few graphics demos the other day.
In particular the plotmath and the persp graphics demos, certain

don't seem to render on the demos.
The plotmath demo displays certain math equations on a quartz
window
that don't render properly, and the persp demo displays a 3D model
of a
mountain with labels on the graph rendered in a certain font. (None
of the
data labels render at all.)
This problem appeared recently, (like last week), and has not
happened
before. I'm fairly new to using the R gui and R in general, so I
don't
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...
