Yes, I did miss the lower right corner of the second page (out of
five) where the Greek letters were demonstrated but certainly did
notice the set relations and arrows section. What I was asking for is
an explicit expansion on the term you used ..."messed up". Your
description of problems does not mimic those that I (and others) were
earlier having, were solved by removed corrupted versions of the
Symbol font. In that instance printing to the Quartz device produced
small empty boxes where Greek letters should have appeared and this
happened also when pdf or tiff were used as output devices.
I'm not sure what demo you're running quite frankly.
How else do you want me to "expound on my difficulties"?
More specifics, especially in light of your next stated limitations.
I've said as straightforwardly as I can what is happening. My
newsgroup client doesn't allow me to post images to this newsgroup,
so it is difficult for me to show you what I mean, so if you've run
demo(plotmath) you should know which fonts I am referring to.
It's not actually a newsgroup but rather a plain-text mailing list.
The default output device is set with the options function:
?device
However, when I try that, I still see a Quartz plot with:
> options(device="X11")
> plot(1)
What I needed to do to get X11 plotting was:
dev.off() # closing the default Quartz device
Then X11 gets the output. If this is desired for every session then
put it in .Rprofile or some other startup mechanism ... see the
Installation and Administration manual and

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

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 fonts
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...
