Phonetic symbols (IPA) in R graphics

Hi Paul,
first thank you for helping out.

Exactly.  The process would be simpler if you drew directly to
PostScript or PDF via postscript() or pdf().

Also, the text() call should be ...

text(10,10,"whatever",family="ipa")

[...]

I'm not sure how you got there.  You've specified the family wrong so I
would expect more "family not found" warnings.  Let me know if this
persists with the correct family specified.

Strangely enough I get the
"family 'ipa' not included in PostScript device"
if I run
text(10,10,"whatever",family="ipa")
while the "PostScriptCIDMetricInfo" error if I run
text(10,10,"whatever",family="InternationalPhoneticAlphabet"")

I get the same behaviour when I write directly to the postscript
device:

postscript(file="whatever.eps")
plot(10,10,type="n")
text(10,10,"whatever",family="InternationalPhoneticAlphabet")
or
text(10,10,"whatever",family="ipa")

I suspect the "PostScriptCIDMetricInfo" error depends on the fact the
the encodings/silipa.enc file contains all values from 33 to 255
(with a few undefines values). Can that be possible?

Thanks,
Giampiero
