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 ...)
thanks

You could do something similar along these lines (untested): <<echo=F>> slidenum <- 1 plotbasename <- "something" plotfilename <- paste(plotbasename, slidenum, ".pdf", sep="") pdf(file=plotfilename) plot(stuff) dev.off() cat("\\only", slidenum, "{\includegraphics{", plotfilename ,"}}\n" ,sep="") @ <<echo=F>> slidenum <- slidenum + 1 plotfilename <- paste(plotbasenema, slidenum, ".pdf", sep="") pdf(file=plotfilename) plot(stuff) dev.off() cat("\\only", slidenum, "{\includegraphics{", plotfilename ,"}}\n" ,sep="") @ If you want toget really fancy, you could wrap most of this in a conveniance function... cu Philipp -- Dr. Philipp Pagel Lehrstuhl f?r Genomorientierte Bioinformatik Technische Universit?t M?nchen Wissenschaftszentrum Weihenstephan Maximus-von-Imhof-Forum 3 85354 Freising, Germany http://webclu.bio.wzw.tum.de/~pagel/
Oops - have to comment my own answer:> <<echo=F>>For this to work it needs to be <<echo=F, results=tex>> cu Philipp -- Dr. Philipp Pagel Lehrstuhl f?r Genomorientierte Bioinformatik Technische Universit?t M?nchen Wissenschaftszentrum Weihenstephan Maximus-von-Imhof-Forum 3 85354 Freising, Germany http://webclu.bio.wzw.tum.de/~pagel/
I don't have an example to hand, but check out the animation package. I have been able to include animations in pdf documents using this and it worked really well - and I think it works with sweave too. I think you could set it up to allow the user to press a button to go through each graphic in turn (rather than a continuous 'movie') - which would mimic the overlay effect in beamer. Worth looking at, because it would then be possible to make some genuine "dynamic" documents. Must have a look myself... All the best.
