Hi Duncan,
I use Eclipse and StatET plus TexClipse and Sweave which comes with the
StatET package.
So fore me it is basically one click as well to produce the pdf from the
.Rnw file.
I installed the MacTex live 2011 version on my computer and thought it might
actually be
easy to find out how and where latex searches for packages. But I did not
find the place
where all this is coded...
First, since this is Mac-related, you would probably get better answers
on the R-sig-mac list.
Second, most latex distributions support both a system 'texmf' tree and
one or more local/user texmf trees, that you can configure with
something like Preferences somewhere in MacTex. On my linux system, I use
~/texmf/ and simply copied Sweave.sty to
~/texmf/tex/latex/misc/Sweave.sty (if my path-memory serves)
No more worries (unless Sweave.sty is changed in a new R distro)
Finally, it does help to RTFM, where you can find other options
under ?RweaveLatex in the Details section.
The LaTeX file generated needs to contain the line \usepackage{Sweave},
and if this is not present in the Sweave source file (possibly in a
comment), it is inserted by the RweaveLatex driver. If stylepath = TRUE,
a hard-coded path to the file ‘Sweave.sty’ in the R installation is set
in place of Sweave. The hard-coded path makes the LaTeX file less
portable, but avoids the problem of installing the current version of
‘Sweave.sty’ to some place in your TeX input path. However, TeX may not
be able to process the hard-coded path if it contains spaces (as it
often will under Windows) or TeX special characters.
The default for stylepath is now taken from the environment variable
SWEAVE_STYLEPATH_DEFAULT, or is FALSE it that is unset or empty. If set,
it should be exactly TRUE or FALSE: any other values are taken as FALSE.
As from R 2.12.0, the simplest way for frequent Sweave users to ensure
that ‘Sweave.sty’ is in the TeX input path is to add
‘R_HOME/share/texmf’ as a ‘texmf tree’ (‘root directory’ in the parlance
of the ‘MiKTeX settings’ utility).
By default, ‘Sweave.sty’ sets the width of all included graphics to:
\setkeys{Gin}{width=0.8\textwidth}.

Let's say I have written the following tiny .Rnw file:
_
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{Sweave}
\usepackage{tikz}
\usepackage{pgf}
\begin{document}
=
sessionInfo()
@
\end{document}
_
I then can go to R and use sweave to translate the .Rnw file into a .tex
file
Once this is done the latex interpreter can be called and because I used
\usepackage{Sweave} Latex knows how to handle the sweave specific code tags.
When I first did this procedure I got the commong error that the Sweave.sty
file could
not be found. I googled and could solve the problem by typing the following
command
into the Mac OS Terminal:
_
mkdir -p ~/Library/texmf/tex/latex
cd ~/Library/texmf/tex/latex
ln -s /Library/Frameworks/R.framework/Resources/share/texmf Sweave
_
What I don't understand now is how does the latex package
\usepackage{Sweave} know that it
has to look at ~/Library/texmf/tex/latex to find the symbolic link to the
Sweave.sty file?
What happens if I change the following line:
ln -s /Library/Frameworks/R.framework/Resources/share/texmf Sweave
to
ln -s /Library/Frameworks/R.framework/Resources/share/texmf Sweave_Link
In the .Rnw file do I have to use then \usepackage{Sweave_Link}?
No. You need to read up on LaTeX documentation, and particularly on the
documentation for your particular implementation, to find out how it
searches for packages, but in general it is looking for the file named
Sweave.sty, and the directory containing it could be named anything.
As an aside, I don't recommend the workflow you describe: it's very
slow and cumbersome. It's much better to tell your text editor how to
run both Sweave and Latex in one command. In the upcoming release of R
2.14.0, this is a single command: R CMD Sweave --pdf. In earlier
releases, it's only slightly more complicated: you need to process the
Rnw to tex, then the tex to pdf using pdflatex or similar. (You can do
more elaborate conversions using my patchDVI package; it's on R-forge,
here: https://r-forge.r-project.org/R/?group_id=233).
