[R] plot greek letter in italic

[Tord Snäll]

Hi,
Could someone please let me know how to plot greek letters in italic.

text(0,14,expression(italic(rho)[italic(f)])) only plots the f in italic and
text(37,40,expression(italic(rho))) doesn't plot rho in italic.

I have checked demo(plotmath), ?plotmath, FAQ, and the archives 
2004-2006 without finding the answer.

I'm using R 2.1.1. and Windows XP.

Thanks!

Tord
