R devel - Mar 2004 - Greek symbols not generated on quartz device (PR#6708)

Full_Name: Mark St. John
Version: 1.8.1
OS: Macintosh 10.3.3
Submission from: (NULL) (63.135.5.86)


After upgrading from Mac OS 10.2.8 to 10.3.3 a program I wrote to generate plots
will no longer display annotated Greek symbols. I'm using parse() and
expression() to convert variable text in to symbols and it would appear that
both functions work reasonably well except that Greek characters are missing.

I have a second computer still running OS 10.2.8 and have confirmed that the
same R program generates figures with annotated Greek symbols properly.

I've only tried this on the quartz device, I've not installed a good
postscript
viewer yet.

Perhaps related: on neither OS 10.2.8 nor 10.3.3 have I been able to get
"italic" text to display properly--it always appears as regular text
despite
trying several different font families.

Symbols fonts has changed encoding from 10.2 to 10.3 and this brokes 
things when using RAqua on different systems.
The new R 1.9.0 fixes this.
Still not able to get styled text (bold, italcs) at the moment.
