Hi. Either split the resulting PDF (either interactively in your PDF reader or using something like pdftk) or do what I have done for my thesis: Have separate Rnw files for each chapter, use a Makefile to generate the tex files, and then have a master latex document for the main project that uses \include to include the relevant chapters. See my Makefile below. This is based on the one discussed in that previous thread.
I also generate standalone "chapters" (which end up as papers). A simple way to do this (if no changes are necessary), is to create separate "master" latex files which only import that single "chapter". For me, a thesis chapter always needs a lot of cutting to create a paper, so I use subversion to create a "branch" and then can merge changes back and forth as necessary. Factor out common functionality into an .R file and import that code (and run it) from within your first <<init>> block. This does mean the same stuff is computed multiple times, but you could choose to cache data on a first run if it is a problem. I don't - the common stuff (like database queries and fixing the data) are quick to perform.
