[R] Italicize Greek symbols in axis

[Joshua Wiley]

That is my understanding also.  I recall reading something once by
Paul Murrell (I think) about using a special font set.  If there is a
font containing italic greek symbols, it seems like that should work.
A (very) poor man's option could just be slightly rotating the
symbols:

par(xpd = NA)
plot(1:10)
text(5, 11, expression(mu), srt = -10)
text(5.3, 11, "+")
text(5.6, 11, expression(beta), srt = -10)

if it is for a title, one runs into additional complications with base
graphcis because the "srt" argument only works for text, not mtext(),
which is why I set clipping to the device region instead of just the
plot region.  I would be interested to learn about more elegant/easy
options too.
