You can use \includegraphics explicitly yourself, and avoid the 
automatic code generated by Sweave.  For example,

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

That generates the figure, but doesn't include it; then

\begin{figure}
\begin{center}
\includegraphics{-testfn}
\caption{The function $f(x) = |x-3.5| + (x-2)^2$.\label{fig:testfn}}
\end{center}
\end{figure}

will do the include.  You need to name the chunk that creates the figure 
for this to be workable, and if you have set a prefix in your 
SweaveOpts, you need to use it in the \includegraphics call.  (Actually 
I forget if the hyphen is needed; I stripped off a prefix from the real 
example to show you this.)
