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).
