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 -- Andy Jacobson andy.jacobson at noaa.gov NOAA Earth System Research Lab Global Monitoring Division 325 Broadway Boulder, Colorado 80305 303/497-4916
