R help - Feb 2011 - Sweave doesn't hand on width of special characters of Computer Modern fonts to LaTeX

Hello R users,

Using R, Sweave and the cmsyase.afm font it is possible to write LaTeX 
documents including R figures with text in the Computer Modern Fonts:

\documentclass{article}
\usepackage{Sweave}
\begin{document}
<<echo = false, results = hide>>CM <- Type1Font("CM",
       
c(file.path("C:/texlive/2009/texmf-dist/fonts/afm/public/cm-lgc",
        c("fcmr8a.afm", "fcmb8a.afm",
"fcmri8a.afm", "fcmbi8a.afm")),
        "./cmsyase.afm"))
pdfFonts(CM = CM)
postscriptFonts(CM = CM)
pdf.options(family = "CM", pointsize = 11)
ps.options(family = "CM", pointsize = 11)
@
<<fig = true, echo = false, include = true>>x <- c(1,2,3)
y <- c(1,2,1)
plot(y~x, xlab = "1 - 3 units")  # The "-" sign here is
@                                # missing in the PDF file!
\end{document}

First of all, Sweave doesn't seem to hand on the width of the "-"
sign
on to LaTex, like the warning is indicating.
Moreover, the font of the text in the graphics looks different from the 
Computer Modern fonts LaTeX is using.

Thanks in advance for your answers,
Julia

Julia,

While not a direct answer to your question, you may find the
pgfSweave driver/package to be interesting.

http://cran.r-project.org/web/packages/pgfSweave/

Among other things, it uses the tikzDevice package for figures, which
will cause the labels and text to use the same font as in your
LaTeX document.

This is very unlikely to have anything to do with Sweave, it's a 
graphics system problem.  You might want to read the article

Paul Murrell and Brian Ripley (2006) Non-standard fonts in PostScript 
and PDF graphics. R News, 6(2):41?47. 
http://cran.r-project.org/doc/Rnews/Rnews_2006-2.pdf

for information.  It looks as though you did everything it recommends, 
except embedding the fonts:  maybe you need to do that.
