I commited a fix to the patched version of R that translates all
backslashes to slashes on windows. This now works for me (on Windows
XP) if the path to R_HOME contains no spaces. For installations in
directories like "Program Files" I still have the following problem: I
can either use

	\usepackage{c:/progra~1/rw1060/share/texmf/Sweave}

or

	\usepackage{c:/program files/rw1060/share/texmf/Sweave}

both of which do *NOT* work with my latex installation
(miktex). Unless somedy has a good suggestion how to solve the problem
my recoomendation is to either install R into a path without spaces or
copy Sweave.sty to some place in your TEXINPUTS path and use
stylepath=FALSE when calling Sweave.
