[R] plot width in Sweave

[Christoph Lehmann]

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
