[Rd] point size in svg

[Spencer Graves]

       Thanks to Peter Langfelder and David Winsemius for their replies.


       It must be Apple specific.  I transferred the R script with the 
svg files between my Mac and a Windows 7 machine.  The svg files created 
on the Windows machine displayed properly on both machines. The svg 
files created on the Mac showed the same tiny fonts on both machines.


       Following David's suggestion, I tried 
svg('cex-svg-Helvetica.svg', family="Helvetica") and 
svg('cex-svg-serif.svg', family="serif") with otherwise the same script 
as before with the same results.


       I will repost this to r-sig-mac R <r-sig-mac using r-project.org>.


       Thanks again to Peter and David.
