A while ago I wrote a package called patchDVI, that allowed
"reverse-search" from the YAP .dvi previewer (or others) to jump
directly to the .Rnw source of an Sweave document.
Recently support for reverse search has been integrated into pdflatex
(through SyncTex). There aren't many PDF previewers on Windows that
support this (only an unreleased version of SumatraPDF, as far as I
know), but I believe Mac OSX previewers have supported it for some time,
and there may be others on Linux or Windows too.
I'd appreciate anyone who is using one of those previewers and who is
interested in this to test the new code. It's available on
http://www.stats.uwo.ca/faculty/murdoch/software/ (near the bottom of
the page).
Including the concordance info into a .pdf needs a patch to Sweave, and
to Sweave.sty:
Sweave should wrap the concordance in \Sconcordance{}, instead of
\special{}.
Sweave.sty should have this macro added:
\newcommand{\Sconcordance}[1]{%
\ifx\pdfoutput\undefined%
\csname newcount\endcsname\pdfoutput\fi%
\ifcase\pdfoutput\special{#1}%
\else\immediate\pdfobj{#1}\fi}
Improvements to this macro would also be appreciated.
