This is neither a bug report, nor a complaint, so I think this is the 
appropriate list.

I am getting an odd font problem with a pdf generated using
 pdf(file = 
"../figures/PCNM.models.larvae.fluor.zoo.stability.2001.and.2002.pdf",
      title="", family="serif", pointsize=10, width=6.75, height=8.625)

The figure produced from my code is here:
<http://www.members.iinet.net.au/~s.mcclatchie/aslo/PCNM.models.larvae.fluor.zoo.stability.2001.and.2002.pdf>
(I can't really send all of the code as there are several subroutines 
for the analysis that are not relevant here anyway).

------------------------------------------------
The pdf loads into acroread or xpdf fine, so is not corrupted, but 
ghostscript gives an error:

ERROR: /invalidfont in --.type1execchar--ESP Ghostscript 815.02:

Also Imagemagick cannot display or convert the file to .png:

--------------------------------
I have all of the true type fonts installed.

Probably the solution is just to use png() rather than pdf(), but I 
thought this problem was curious enough to report.
