R help - Oct 2003 - plot width in Sweave

Hi

I didn't find this in the manual: I need to change the width of a plot
while I use sweave, so which command/parameters should I insert below,
to change the width of a plot

\begin{figure}[htbp]
  \begin{center}
<<echo=TRUE, fig=TRUE>>plot(Re(q),ylab
="",type="o",col="blue",lwd=1, sub=mystring)
@     
    \caption{Original stick function (stimulus train)}
  \end{center}
\end{figure}

many thanks

christoph

Depends what exactly you want to change. If you to change the width of 
the eps/pdf file you could say

  <<echo=TRUE,fig=TRUE,height=4,width=6>>
as you would do in a postscript() or pdf() call in R.


If you want to increase the width of the plot in LaTeX, you could do

  \setkeys{Gin}{width=0.8\textwidth}

which corresponds to the setting of

  \includegraphics[width=0.8\textwidth]{mygraphic}
