This may be asking too much, but I'm wondering if anyone has a
solution (even a hack) for creating multiple (overlay) plots in an
Sweave file and post-processing the overlays in beamer appropriately.
For example, suppose I have a series of figure blocks in my .Rnw file:
<<plot1,fig=TRUE>>=
[stuff]
@
<<plot2,fig=TRUE>>=
[stuff]
@
<<plot3,fig=TRUE>>=
[stuff]

These three blocks create three figures that I want to have appear as
a series of overlays in the final PDF file.
Sweave outputs the following LaTeX code:
\includegraphics{plot1}
\includegraphics{plot2}
\includegraphics{plot3}
and I need to turn it into
\only<1>{\includegraphics{plot1}}
\only<2>{\includegraphics{plot2}}
\only<3>{\includegraphics{plot3}}
I have few enough of these that I've been modifying them by hand
(couldn't easily come up with the appropriate sed/awk incantation); it
works, but it's annoying and error-prone. I could spend some more time
hacking it, but I wondered if anyone else had already solved this ...
(Brief googling of "beamer+Sweave+overlay" didn't find an obvious
answer, but I might have missed something ...)
You can put the \only calls in the Rnw, e.g.
\only<1>{
<<fig=true>>=
m <- 1
<<plotchunk>>
@
}
\only<2>{
<<fig=true>>=
m <- 2
<<plotchunk>>
@
}
