Oops - missed to include the following:

To generate PNGs, you can do it manually in the Sweave document, e.g.

<<myFigure>>=
png("myFigure.png");
plot(1:10);
dev.off();
@

\begin{figure}
 \resizebox{0.9\textwidth}{!}{\includegraphics{myFigure}}
 \caption{A caption.}
 \label{fig:aLabel}
\end{figure}
