Since 0x2d = 45, it looks like those fonts are missing 'minus'. See
?postscript for more details on encodings (and 'minus' vs 'hyphen').
'Linux' is too imprecise here. but I looked at my TeXLive 2009
installation (in a different place) and fcmr8a.afm did not contain
'minus'.

Hi!
On Linux I try to produce pdf graphs with computer modern fonts so that they
look nice in LaTeX documents. I run for example:
------
CM <- Type1Font( "CM",
c("/usr/share/texmf-texlive/fonts/afm/public/cm-lgc/fcmr8a.afm",
"/usr/share/texmf-texlive/fonts/afm/public/cm-lgc/fcmb8a.afm",
"/usr/share/texmf-texlive/fonts/afm/public/cm-lgc/fcmri8a.afm",
"/usr/share/texmf-texlive/fonts/afm/public/cm-lgc/fcmbi8a.afm",
"./cmsyase.afm" ) )
pdfFonts(CM=CM)
pdf( "test.pdf", width = 5, height = 4, family = "CM" )
plot(c(-1,0,1))
dev.off()
-----
which works fine except that R has problems with the minus sign for the
labels and axis and I get the following warnings:
---
... font width unknown for character 0x2d ...
---
The minus signs are directly printed on the numbers, not in front of them.
I suspect that you are not actually looking at the right font (given
that it seems not to have a minus sign): how did you view the PDF?
Does anybody know what I am doing wrong?
Thanks already now,
Markus.
