[R] CM Fonts in PDF output

[Prof Brian Ripley]

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'.

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?
