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.
