I use Sweave and could not have explained it better than Michael did.  
It is a really nice option to document your analyses. Otherwise I  
have the bad habit of getting countless plots and analyses and a few  
months later I wonder what was done in what order and exactly for  
what reason. With Sweave I have a nice document explaining the whole  
thing. Better yet, you need to correct your data: you recompile your  
Sweave document, then the resulting tex document, and everything is  
redone with the corrected data.

For a paper or a report, I do not work this way, I write it in LaTeX  
only because I'll probably only need to include a few pdf graphics  
produced with R. However my reason for doing this was that TeXShop  
does not have the proper syntax highlighting for Sweave, and  
TextWrangler either (I normally use the former for tex document and  
the latter for R documents. However I'll explore what Charilaos  
Skiadas has said about TextMate, maybe I'll use Sweave even more  
often if I get proper syntax highlighting.
