R help - Nov 2008 - Sweave: side by side dynamic graphs

Hi all:
I'm trying to create some side by side dynamic graphics on the same page but
I am running into some problems. I am able to create side by side figures only
if I import them into my PDF. see the example bellow:

\documentclass[12pt]{article}
\usepackage{color,cite,graphicx}% to put in axodraw
\usepackage{latexsym,amssymb,epsf}
\begin{document}
%Import two figures side by side. Please Replace the 'bar' picture with
any
% jpeg picture to make this example reproducible.
\begin{figure}[h]
\centerline{\mbox{\includegraphics[width=3.00in]{bar}}
\mbox{\includegraphics[width=3.00in]{bar}}}
\end{figure}

% I would like to create two dynamic graphics here side by side
%but isn't working.
\begin{figure}[h]
\centering
<<fig.R,echo=F,fig=T,width=2.5,height=2.5>>plot(1:10}
@
\caption{This is the first graph}
\end{figure}
\begin{figure}
\centering
<<fig.R,echo=F,fig=T,width=3,height=3>>plot(1:15)
@
\caption{This is the second graph}
\end{figure}
\end{document}

Thanks for your help

Thanks for the example; there was a minor typo so that it did not run
"plot(}",
and a major problem that could have caused serious problem (happens to me quite
often due to copy and paste)

<<fig.R,echo=F,fig=T,width=2.5,height=2.5>>
You must give the << sections with graphics different names, otherwise the
wrong
picture will be used. 

For side-by-side, you simply plot side by side, or use minipages when captions
are needed for both figures. In the first case, trellis graphs are much more
space-conservative.
