For some reason that doesn't work for me. reftex-toc is only aware of
the entire multi-document structure if I use;

%%% Local Variables:
%%% mode: latex
%%% TeX-master: "master.tex"
%%% TeX-default-extension: "tex"
%%% End:

whereas;
%%% Local Variables:
%%% mode: latex
%%% TeX-master: "master.Rnw"
%%% TeX-default-extension: "Rnw"
%%% End:

leaves reftex-toc only showing the structure for whatever child document
is in the buffer. Maybe my Emacs is too old (24.3.1)? Although I have
fixed my referencing problem by setting reftex-default-bibliography in
~/.emacs (not ideal but it works for now).

The other thing regarding reftex-toc is the inclusion of Rnw parts via
knitr;
<<chunk-name, child='child.Rnw'>>=
@

It seems to me that reftex-toc is unaware of these inserts. Is there a
way to bring these inserts into the reftex ToC list?

Thanks,

Dave.
