[R] degree symbol using X11 on OSX

[Andy Jacobson]

Howdy,

Using the scheme in plotmath, I can no longer get the degree symbol  
for my on-screen plots, using X11 on OS X.  I instead see an upper- 
case upsilon (I think).  This is reproducible using  
"demo(plotmath)".   A figure drawn with this faulty symbol produces  
correct postscript (i.e. with a degree symbol) when I use dev.copy to  
write it to an eps file.

I'm using R version 2.8.1 Patched (2009-01-19 r47650) on an intel Mac,  
fully updated OS X 10.5.7.

Help appreciated,

Andy
