You say that you call R code embedded in your LaTeX document. I tend to think of it as LaTeX embedded in my R code. I think the answer to your question is 'no', but there might be ways to work around it.
I use AUCTeX in emacs and can select a region of foo.sw and run latex on that. This works fine although you won't have access to R objects using \Sexpr{}. In practice I tend to use <<eval=FALSE>> to "comment out" R code chunks that I have run previously if I do not need to update or recreated their objects. This means that running Sweave on foo.sw then does not take too long to run the R chunks that do need to be run, i.e. foo.tex is created pretty quickly. Running latex does not then usually take long either. I use search and replace or the chunk navigation hotkeys (e.g. M-n g) when I need to change <<eval=FALSE>> to <<eval=TRUE>>. Creating a Makefile to run R with Sweave (as indicated in the FAQ in the Sweave manual) and then latex the resulting foo.tex should work pretty well to automate the process. I am still new to Sweave, but have had a lot of fun with it so far. I use emacs with ESS, Sweave, RefTex mode, LaTeX mode and Prosper - a presentation class that creates PDF presentations which (can if you want) look like MS Powerpoint presentations but with the advantage of LaTeX formatting. All the tools I need for analysis, writing, and presentations working together. My first serious use of this combination was last week. I had a foo.Rnw file which produced both my presentation and accompanying notes to handout. I discovered a mistake in my R code shortly before giving my presentation, fixed it, Sweave'd the file and updated my presentation and notes painlessly. A nice way to work. Dave.
