[R] Correct Computer Modern font in postscript(..) output

[Mark Van De Vyver]

Brian,
Thanks for the reponse.  I apologise if I gave the impression of being
accusatory - not my intention.  My point was that when I use italic(), in R
with ComputerModern, I get output 
different to the output I get when I use \italic in TeX/LaTex.  I'm neither
an R nor TeX pro (for want of time not interest), so I simply expected the
two to be the same.  Brian states the current output is the intended
behaviour, which is fine.
Thanks
Mark
