I am on 10.5.8 using the default Quartz screen device. When I followed
your advice I found that there were two listings for Symbol/Regular
and that one of them was displaying a blank page within Font Book.app.
I remove that one, restarted R (after getting pages full of warnings
in my first re-test) and now I am seeing Greeks again. Somehow a blank
Symbol font got installed/corrupted or something. Thanks.

David,
which graphics device and which OS are you talking about? For Quartz
it is the Symbol font that is used (if I remember correctly) -
please check your Font Book and make sure it's not disabled.
Cheers,
Simon

Dear MacRs;
I have been having this problem for a while, but thought that when
I updated to 2.11.1 that it might get fixed, but just did that and
it persists. When I use plotmath functions, I see little empty
boxes where I should be seeing theta's and phi's:
require(graphics) # the first plotmath example
x <- seq(-4, 4, len = 101)
y <- cbind(sin(x), cos(x))
matplot(x, y, type = "l", xaxt = "n",
main = expression(paste(plain(sin) * phi, " and ",
plain(cos) * phi)),
ylab = expression("sin" * phi, "cos" * phi), # only 1st is
taken
xlab = expression(paste("Phase Angle ", phi)),
col.main = "blue")
axis(1, at = c(-pi, -pi/2, 0, pi/2, pi),
labels = expression(-pi, -pi/2, 0, pi/2, pi))
# -- no phi's or pi's or warnings ---
How do I identify which library should be replaced or repaired or
added to my PATH or which option set?
Have searched archives and FAQs, but maybe I'm not using same terms
or understanding what I am being told.
