Not really looking at  your .emacs  {lack of time ..}, but I see
you are using the 'synctex' option -- though  quite a bit
differently than we did (below).

But: Yes, it is possible, I have done this -- with prompting and
help from Marius Hofert (in CC) who I think uses this much more
regularly than I do.

It is important to use "synctex" when building the final PDF.
Also important is to use R package "patchDVI" to collaborate with synctex.

We've used ESS for editing and running R etc, but used a
Makefile for final Sweaving and pdf production, also because the
final pdf was made from several *.tex, *.Rnw, *.R  *.sty ... files.

Here are relevant parts of the Makefile
where you should note the Rscript call to  patchDVI::patchSynctex() :
----------------------------------------------------------------------

PDFLATEX0 = pdflatex
PDFLATEX = $(PDFLATEX0) --shell-escape -synctex=1 -file-line-error
#TEXI = PDFLATEX='${PDFLATEX}' ${R_PROG} CMD texi2dvi -p
TEXI = PDFLATEX='${PDFLATEX}' texi2dvi -p
SWEAVE  = $(R) CMD Sweave --encoding=utf-8
STANGLE = $(R) CMD Stangle --encoding=utf-8
ifneq ($(strip $(RNW)),)
 PATCHSYNCTEX = `$R RHOME`/bin/Rscript -e "patchDVI::patchSynctex('$*.synctex')"
endif

pdfDeps = $(RNW:=.tex) $(TEX:=.tex)  Sweave-JSS-prelim.R *.bib


[...............]

%.pdf: %.tex $(pdfDeps)
	$(TEXI) $<
	$(PATCHSYNCTEX)

%.tex: %.Rnw $(R_AUX)
	@echo; echo; echo '--- Sweaving '$<': ------------------------------------'; echo;
	$(SWEAVE) $<

----------------------------------------------------------------------

I hope this will help
