Sweave (PR#2142)

# 
In the 'RWeaveLatexSetup' function in the 'tools' package in R 1.6.0 , the
code below does not work (pdflatex can't find 'Sweave.sty'):

if (stylepath)
        styfile <- file.path(R.home(), "share", "texmf", "Sweave")
    else styfile <- "Sweave"

In R 1.5.1, that was:

if(stylepath)
        styfile <- file.path(.path.package("tools"),
                             "Sweave", "Sweave")
else
        styfile <- "Sweave"

and that was working.

The path is correct (I want to have Sweave.sty in
$R_HOME/share/texmf), but the install procedure has a bug: Sweave.sty
does not get installed properly when builddir != srcdir. This has been
fixed in both the devel and patched version of R.

As a quick fix for 1.6.0: please copy Sweave.sty manually to
$R_HOME/share/texmf.

Thanks a lot for the bug report,
Fritz

Thanks, Fritz, for your answer.
Yes, but  'file.path(R.home(), "share", "texmf", "Sweave")' on my MS-Windows
box gives "C:\\R\\RW1060/share/texmf/Sweave".

With that, you get '\usepackage{C:RRW1060/share/texmf/Sweave}' in the tex
file. The problem seems to be with the 'R.home()' output on MS-Windows.

'file.path(.path.package("tools"), "Sweave", "Sweave")' was giving
"C:/R/RW1060/library/tools/Sweave/Sweave" which is OK for pdflatex.

Anyway, thanks a lot for Sweave which is really great (for the moment, as I
need it working, I have just put back the old stylepath code in tools).

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.

Dear Friedrich et al.,

Why not make the default location for installing the Windows version of R 
"c:\R" rather than "c:\Program Files\R", thus avoiding this and other 
potential problems? Perhaps there's some consideration of which I'm unaware.

Regards,
  John
