[R-SIG-Mac] [R] Mac OS X R.app has trouble rendering certain fonts.

[David Winsemius]

As far I can remember you have never offered either sessionInfor(),  
nor a sample problem in R code, nor an explicit description of what is  
being produced, nor a pdf file that can be examined. I have run  
demo(plotmath) and it appears not to exercise fonts ot any exceptional  
degree .... no theta's, tau's or gamma's. Do you care to exapnd on  
your difficulties?
