R devel - Jul 2006 - Sweave processes comments incorrectly (PR#9073)

Full_Name: Kevin R. Coombes
Version: 2.1.0
OS: Windows XP
Submission from: (NULL) (143.111.22.24)


I have a source file "devel.Rnw" that uses the LaTeX foils class and
ppower4 to
produce a PDF presentation file.  It starts with a commented note to myself as
follows:

%%%% begin source example %%%%
%
%  Remember to update the hypersetup to include individual lecture
%  titles, change the leftheader to include the lecture title, and
%  then start at \begin{document} ....
%  Also, produce a printable (black and white version) according
%  to the cues immediately following \begin{document}.
%  Compile this document with:
%    pdflatex <filename>.tex
%  and then:
%    ppower4pb <filename>.pdf <filename>.pdf
%
\documentclass[Screen4to3,25pt,headrule,footrule]{foils}
\usepackage[pdftex]{color}                  %for colors
\definecolor{Teal}{rgb}{0.0,0.47,0.46}
%% more colors and packages omitted from bug report
\begin{document}
\hypersetup{pdfpagetransition=Replace}

%%%% end source example %%%%

When processed using Sweave, the \begin{document} comments are expanded to
actual LaTeX commands, causing a later latex to fail.  That is, the output of
running Sweave() on this file begins:

%%%% begin source example %%%%
%
%  Remember to update the hypersetup to include individual lecture
%  titles, change the leftheader to include the lecture title, and
%  then start at \usepackage{c:/R/rw2010/share/texmf/Sweave}
\begin{document} ....
%  Also, produce a printable (black and white version) according
%  to the cues immediately following
\usepackage{c:/R/rw2010/share/texmf/Sweave}
\begin{document}.
%  Compile this document with:
%    pdflatex <filename>.tex
%  and then:
%    ppower4pb <filename>.pdf <filename>.pdf
\documentclass[Screen4to3,25pt,headrule,footrule]{foils}
\usepackage[pdftex]{color}                  %for colors

             ^^^^^

Please note that this version of R is very outdated, please only
report bugs which are verified for the most recent version of R (in
this case it was still there, though).

Thanks a lot for the bug report, fixed in r-patched and
r-devel.

Best,
