[R] Using system fonts in MacOS

[Daniel J Farrell]

Dear r-help,

I am using R for MacOS (R 2.9.1 GUI 1.28 Tiger build 32-bit (5444))  
and would like to be able to use MacOS system fonts for the labels on  
my plots. So far I have been unsuccessful, to get this to work.

Reading the help I found the quartz() and quartzFonts() commands. In  
an attempt to set the font family I have tried this,

quartz(family="Times-Roman"),

and also this,

quartz.options(family="Times-Roman").

This opens a new Quartz window, but the labels are still in the  
default font, when I make a new plot.

I have two question:
(1) Why doesn't the quartz(family="Times-Roman") make the fonts change?

(2) Is it possible to use any MacOS system fonts with R and the Quartz  
device window?

Best regards,

Daniel Farrell
