I noticed noone had attempted to answer this. Sweave is a documented  
source tool, at least that's what I understand from a message to this  
list from 2004 (correct me if I'm wrong). The situation is similar to  
web/noweb/cweb where the source that is compiled and the source that  
you write are two different things.

I can see two solutions: use an editor that will check whetehr a file  
was modified on disk, and re-read as needed (BBedit, TextWrangler,  
TextMate (I think)). AppleScript will then allow you to compile and  
preview from this generated source.

Another solution is to use R's shell integration (system(), I think,  
there must be some function to call command line utilities), and  
integrate with TeX at that level. You can then use the "open" shell  
command to open the pdf and view the result. This way your generated  
sources never open in a text editor, and the bug is circumvented.

By all means visit the TeXShop sourceforge page and file a bug report  
(sync with disk is the appropriate term).
