R help - Jul 2003 - Sweave: pass scale parameter to includegraphics?

Hi all

I'm using Sweave and find it a treat.  But one
question:

I use Sweave to create my pictures which are
automatically included into LaTeX.  For example, 
in the file  test.Snw,  I may have:

% LaTeX stuff
\begin{figure}
<<fig=true,width=5,height=5>>x1 <- seq(1,5, length=10)
x2 <- sin(x1)
plot(x1,x2)
@
\caption{Plot}
\end{figure}
% More LaTeX

This produces the LaTeX file test.tex with the
(example) chuck:

% LaTeX stuff
\begin{figure}
\includegraphics{test-001}
\caption{Plot}
\end{figure}
% More LaTeX stuff

But what if I want the chunk to be, for example,
   \includegraphics[scale=0.6]{test-001}
rather than the standard, no frills \includegraphics 
command?  (Why?  Because I create a picture that I
want small!  Changing  width  and  height within the
<<>>= only changes the appearance of the picture--it
alters the x11 window the plot is produced in, not
the final size in my document.)

How can I inform Sweave to create this in the
LaTeX code (not universally, but in the occasional
picture)?  More generally, how can I inform Sweave
to pass these types of parameters to the 
\includegraphics command?

I have searched archives and all the (obvious to me) 
places, but haven't found the solution.

Thanks again,

P.

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
