Yes, I do use make for this (ironically I deleted that information
from my original message in an affort to stick to the relevant
essentials).  The problem is not so much the lost of C-cC-n as that
all the information that AUCTeX and RefTeX glean from the .aux files
of the master file and its dependencies is also lost to the .Rnw
buffer.  That causes that the automatic labelling and referencing and
citing stuff to stop working, and I am pretty dependent on those.

I'm rushing out the door right now, but your suggestions for f3 and f4
don't seem to be solving my problem either; I'll play with those more
