R help - Jun 2010 - text with greek letters

Hi,

I am having troubles in putting greek letters and formatted text in a plot


m=1.43432
sig=0.124333
text(10.5,0.07,sprintf("<Sigma>=%1.2f±%1.2f",m,sig))
I would like to have the greek letter Sigma followed by the formatted numeric
values of m and sig.
Does someone know a solution?

thanks a lot
Thomas
