[R] Sweave: pass scale parameter to includegraphics?

[Christophe Declercq]

Peter,

To set the width of included graphics in your LaTeX document, see the Sweave
manual: http://www.ci.tuwien.ac.at/~leisch/Sweave/Sweave-manual-20030624.pdf

'It also sets the default LATEX figure width (which is
independent of the size of the generated EPS and PDF files).
The current default is \setkeys{Gin}{width=0.8\textwidth} if
you want to use another width for the figures that are
automatically generated and included by Sweave, simply add a
line similar to the one above after \begin{document}.'

Hope it helps.

Christophe
