Dear Duncan:

Thanks for the tip. This is very useful to me.

Just to clear up the filename question, I worked up an example for
testing.  For me it is necessary to include the name of the Rnw/tex
file as a prefix in the includegraphics command.  Maybe that's just
me, or Ubuntu, or TexLive2007.

Here is a working file SweaveExample.Rnw.  In order to make this work,
you see the figure names in includegraphics.

\documentclass[english]{article}
\usepackage[T1]{fontenc}
\usepackage[latin9]{inputenc}

\usepackage{babel}

\begin{document}
<<testfn, fig=true, include=false>>=
curve(sin, from = 1, to = 5)
@

<<testfn2, fig=true, include=false>>=
curve(sin, from = 1, to = 5)
@

%
\begin{figure}
\caption{My Figure}
\includegraphics{SweaveExample-testfn}
\end{figure}

%%works without float too:
\includegraphics{SweaveExample-testfn2}
\end{document}
