That's interesting, thank you very much, Thomas, for the extra
explanation!
As you know (but your text above could be read differently) this
bug ... quite long standing! ... seems to be much wider spread
than just (Open)SuSE. I have seen and still see it on Redhat
(RHEL 5) and many Ubuntu versions too.
And indeed, the workaround recommended (somewhere) in the above
URL is working for me too:
Add the following (without the "-----" lines) to your
~/.fonts.conf file (or create such a file) :
--snip---------------------------------------------------------
<alias binding="same">
<family>ZapfDingbats</family>
<accept><family>Dingbats</family></accept>
</alias>
--snip---------------------------------------------------------

[Moved to R-Devel] Same problem on Fedora 8 through 10. The snippet Martin shows fixes the problem on those systems also. It would be very useful to have this documented somewhere either as a note in ?pdf or in perhaps in the R Installation and Administration Manual, until such a time as distro's fix these problems. To that end I'll also be filing a bug against fedora 10 when I get home (and confirm it is still there) as my system has an entry for 'Zapf Dingbats' but not 'ZapfDingbats' which causes the problems on my boxes. Great to finally have worked around this issue --- not that it was R's fault. I had completely missed the useDingbats argument of pdf(). The Rd file does however make it sound that the default (TRUE) is there to fix the problem of broken PDF viewers, where surely it is the FALSE state that fixes the problem, or perhaps what was intended was that it is the argument itself that was provided to fix buggy viewers. I'd be happy to patch any/all of those sources if someone in R Core would be willing to take a lot and possibly apply them? All the best, G
