[R] Sweave doesn't hand on width of special characters of Computer Modern fonts to LaTeX

[Erik Iverson]

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.
