[R] Greek characters in plots

[michael watson (IAH-C)]

Hi

I am running an R script that creates 100s of graphs, and I need to use
the greek CAPITAL letter delta in the mtext() function.

I got as far as expression(delta) but this gives me the lowercase
version.

Can anyone help?  I'm using R 2.7 on Windows XP
