(I don't get two copies from "open"ing it twice; there's something different about the way TeXShop opens it as a preview than opening it just as a file on its own.)

No, I start with Chapter.Rnw, and Book.pdf gets produced.

They are very simple:  I just pass a function call on the command line 
to Rscript, e.g.

Rscript -e 'SweavePDF("Chapter.Rnw")'

and R runs Sweave on Chapter.Rnw, which tells it that Book.tex is the 
main .tex file, so then it runs pdflatex on Book.tex, which produces 
Book.pdf.   Presumably what SweavePDF does could all be done via 
makefiles, so I guess latexmk could do it as well, but there would still 
be the problem that I start from asking to typeset Chapter.Rnw, and end 
up producing Book.pdf.
