You need to print the plot - something like this:

<<echo=FALSE,results=hide>>=

library(nlme)

fm1 <- lme(follicles ~ sin(2*pi*Time) + cos(2*pi*Time), Ovary)

trellis.device(color=FALSE)

@

\begin{figure}
   \centering
<<fig=TRUE,width=11,height=5>>=

print(plot(ACF(fm1, maxLag = 10), alpha = 0.01))

@

\end{figure}
\begin{center}
\end{center}
