[R] Computer Modern

[Mr Derik]

Thank you for your help.

I've read all the documentation I can find and I still can't get this to
work.

postscriptFonts()

in my console produces a list of fonts already mapped yes?

one of which is:

$ComputerModernItalic
$family
[1] "ComputerModernItalic"

$metrics
[1] "CM_regular_10.afm" "CM_boldx_10.afm"   "cmti10.afm"       
"cmbxti10.afm"      "CM_symbol_10.afm" 

$encoding
[1] "TeXtext.enc"

attr(,"class")
[1] "Type1Font"

So modifying the code of Paul's website:

pdf("destructiontest.pdf")
par(family="ComputerModernItalic")
demo(plotmath)
dev.off()

Should give me what I want. Instead I get a file which can't be opened and
25 warnings which all look like this:

25: In text.default(2 * c - 0.5, -r, title) :
  font family not found in PostScript font database

I've tried the "Test full Adobe Symbol font" code off Paul's website with
the fonts loaded into my working dir as described. I get 35 warnings of the
type:

1: In grid.Call.graphics("L_text", as.graphicsAnnot(x$label),  ... :
  font width unknown for character 0x7f

and a pdf with dots in place of every character.

I can open the example pdf on Paul's website and see the correct CM font so
my viewer must be working.

Any other ideas would be welcome.
