R help - Mar 2004 - Correct Computer Modern font in postscript(..) output

Hi,
I'm trying to get the correct font used when generating italic text in an R
grahic.  I have a set of labels that print correctly except it seems the
italic text is justr a slanted version of the TeX computer modern normal
font...  I'm using R v1.8.1 on Windows XP, and I get the same result if I
build the pdf using Adobe Acrobat or using MikTeX

The labels:

grpNames<-c(expression(paste("lo ", italic(d[n]))),
expression(italic(d[n])), expression(paste("hi ", italic(d[n]))),
            expression(paste("lo ", italic(LM[1]))),
expression(italic(LM[1])), expression(paste("hi ", italic(LM[1]))),
            expression(italic(d[n])), expression(italic(LM[1])),
expression(italic(LM[2])))

The postscript command:

postscript(file = "Rplots.ps",
           onefile = F, height=6,width=10,
           paper="a4",
family="ComputerModern",bg="transparent",
           horizontal=F, pointsize=10,
           print.it=F)

Is this the best currently available, or is there some way to get the
correct font used when using italics?

TIA
Mark

family="ComputerModern" gives you CMSL10, which is the `correct
font'.
>From src/main/devPS.c:
    /* Computer Modern as recoded by Brian D'Urso */
    { "ComputerModern",
      {"CM_regular_10.afm", "CM_boldx_10.afm",
"CM_italic_10.afm",
       "CM_boldx_italic_10.afm", "CM_symbol_10.afm"}
    },

and CM_italic_10.afm specifies CMSL10: there is no italic font in standard 
Computer Modern, and the `correct font' is the one the designer intended.

What did you think the `correct font' was?

Please do read the posting guide and its references, and try to write more 
informative (and less accusatory) messages.

Well, that is `building' a postscript file, not PDF: if you want PDF you 
should be using pdf().
