I am trying to get emacs and AucTeX to synchronize my .Rnw source file with evince to go to comiled text from source and back.
I have already checked that the synchronization works fine between a .tex source and a PDF.
My .Rnw file starts with :
\documentclass[a4paper,twoside,12pt]{article}
\synctex=1 %% Should force concordance generation
\pdfcompresslevel=0 %% Should force avoidance of PDF compression, which patchDVI does
\pdfobjcompresslevel=0 %% not handle
<<include=FALSE>>= %% Modificaton of what Sweave2kinitr does
## opts_chunk$set(concordance=TRUE, self.contained=TRUE) ## No possible effect
opts_knit$set(concordance=TRUE, self.contained=TRUE) ## Seems reasonable
@
%% \SweaveOpts{concordance=TRUE} %% That's where inspiration came from
Consider the following log (unrelevant parts edited) :
> options("knitr.concordance")
$knitr.concordance
[1] TRUE
> opts_knit$get("concordance")
[1] TRUE
> knit("IntroStat.Rnw")

Let's do that again to fix references :

It appears that something in the set of tools does not work as advertized : either dviPatch does not recognize legal concordance \specials or pdflatex dfoes not generate them. It does generate something, however...
I checked that the resulting PDF enables evince to synchronize with the .tex file, but not in the .Rnw file. Furthermore, when the .Rnw file is open in emacs, starting the viewer with 'C-c C-v View" in AucTeX indeed starts the viewer (after requesting to open a server, which I authorize), but the viewers is empty, and i get this :
"TeX-evince-sync-view: Couldn't find the Evince instance for file:///home/charpent/Boulot/Cours/ODF/Chapitres/Ch3-StatMath/IntroStat.Rnw.pdf"
in the "Messages" buffer.
So we have a second problem here.
A third one would be to integrate all of this transparently in the AucTeX production chain, but this is another story...
I'd really like to keep emacs as my main tool for R/\LaTeX/Sage work, rather tha switch to RStudio, which probably won't like much SageTeX and othe various tools I need on a daily/weekly basis...
Any thoughts ?
