One of the things I love about emacs is being able to specify a master file, then compile an included .tex file - I just use C-c C-b
For sweave documents, I have the following layout:
master.Rnw
\SweaveInput{chapter1}
\SweaveInput{chapter2}
\SweaveInput{chapter3}
I would like to use the same idea as C-c C-b to only sweave/latex chapter1. Is this possible in emacs?
I am no expert on Sweave, but it seems to be integrated in the ESS package with an Rnw and Snw mode where you can have it run Sweave or R on the buffer code directly. So that might be what you want if it's just to preview the sweave file result.
I also found details on integrating ESS more tightly with AUCTeX here. It's not tested, but C-c C-c is mapped to run the command on the master file, so it might work for you.
While this is not a complete answer, I hope it helps. I put it in WIKI mode so you can add more details if you find anything more.
I doubt this sort of thing is possible, because running tex just on chapter 1 won't work, since it will need the common preamble which is presumably in the master document. And if you run tex on the master, then it doesn't know to only do the first chapter.
One way to do what you want is to use \includeonly to tell the compiler which files to include. (I expect the \SweaveInput has a similar command...) See here for some details
If the problem is you want emacs to treat .Rnw files like .tex files, try adding this to your .emacs:
(add-to-list 'auto-mode-alist '("\\.Rnw~?$" . latex-mode))
C+c C+b copies the preamble and the "included file" into a temporary file called _region.tex. It then latexs that file. Of course, chapter numbers, etc, are off. But it's very handy for quick checks.

C-c C-c. Why doesn't exactly the same thing work with sweave documents? I'd have thought the process would be identical...

M-n s and it doesn't (seem) to have any idea about the concept of a master file. I tried to hack my .emacs, but things quickly got messy. For example, auctex expects .tex file extensions. At this point, I thought there must be a better way.

C-c C-b type Other and then try typing Sweave at the next prompt. Does this work?
