[R] uppercase greek and plotmath

[Jarrod Hadfield]

Hi,

I cant seem to get some uppercase greek symbols (e.g. Delta) using   
plotmath.  I'm on version R 2.7.0 (2008-04-22) Fedora Core 7 (34   
bit).  I have installed a whole heap of fonts, but still no luck, and  
any help would be appreciated.

  Cheers,

Jarrod
