Have you tried specifying an absolute path in prefix.string instead of a
relative one?
HTH,

Good point! This actually solves the problem, I just wanted to avoid
this as I wanted to send it to someone else... so I just reordered the
files and it works.
Solutions given by Duncan work also, nice!
I agree with you Duncan, it is not a big problem, and doesn't need at
all priority, but mentioning it is maybe worth in the doc, especially if
this could avoid someone to lose those two hours I lost with this
Thanks to all you both!

Hello
I think there is a conflict between setwd() and
\SweaveOpts{prefix.string=}. In the same document, those both command
get Sweave confuse the files and directories. See:
say my .Rnw document is in File1
If one inserts some setwd() for another file:
-setwd(File2)
then the command \SweaveOpts{prefix.string=graphics/Rplots} will
search the "graphics" folder in File2 because of command setwd(File2)
and not in File1 where the .Rnw file is and as is said in Sweave
Manual A10.
Hence Latex get really confused and does not work anymore: the
command \includegraphics looks for folder "graphics" in the usual
File1 but those can have been stored in File2.
I tried to add some:
\usepackage{graphicx}
\graphicspath{{../File2/graphics/}}
but resulot was not so convincing
Is there anyway to avoid this? Thanks!
You could use a fully qualified prefix, so it doesn't matter what the
current directory is when you save a plot.
Or you could avoid setwd().
Or you could change back to the original directory before drawing a plot.
It would probably make sense for Sweave to do the last of these
internally: it is mixing up characteristics of the session it's
running in with characteristics of the session it is running.
However, this is a pretty strange case, and I'm not sure fixing it
will be a high priority.
