Thanks a lot yuor advice works, here is an actually working example of an .rnw file, where the graphs are stuffed in a subfolder:  

\documentclass{article}
\begin{document}
\SweaveOpts{include=FALSE}

This is an experiment with two plots.

Here is the first:
<<CHUNK1, fig=TRUE, echo=TRUE, eps=FALSE, width=3, height=7, prefix.string=./graph/xx>>=
x<-seq(-2*pi, 2*pi, .1)
plot(x, sin(x), type="l", lwd=4)
@
And here is the second:
<<TJUNK2, fig=TRUE, echo=TRUE, eps=FALSE, width=7, height=7, prefix.string=./graph/xx>>=
x<-seq(-2*pi, 2*pi, .1)
plot(x, cos(x), type="l", lwd=4)
@
The result should be two graphs side by side: \begin{figure}[h]

  \centering
  \includegraphics[width=0.27\textwidth]{./graph/xx-CHUNK1} \hfill
  \includegraphics[width=0.63\textwidth]{./graph/xx-TJUNK2}
  \caption{\it Here is the caption.}
  \label{fig:Tschunks1und2}

\end{figure}

\end{document}
