Hi,
I have found an unwanted feature in the Rd to LaTeX convertion
regarding \preformatted inside a \section. I have created an Rd
example below, which generates an error in the following 'R CMD check'
step
* creating aroma.affine-manual.tex ... OK
* checking aroma.affine-manual.tex ... ERROR
LaTeX errors when creating DVI version.
This typically indicates Rd problems.
I believe the Rd code itself explains the details, the reasons, and
the work around. Should it be reported as a bug?
Best wishes

Begin Rd example
-------------------------------------------------------
\name{Example}
\alias{Example}
\keyword{documentation}
\title{Example}
\description{
Example
\preformatted{
No problems here!
}
}
\section{A section}{
If an 'preformatted' Rd environment (or whatever it's called)
within a 'section' is not followed by a newline before the end
of the 'section' the LaTeX version of it generated by \code{R CMD
check}
will end like:
\preformatted{
\end{verbatim}\end{Section}
}
and the LaTeX compiler will complain saying:
\preformatted{
! LaTeX Error: \begin{list} on input line 49 ended by \end{document}.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...
l.59 \end{document}
?
}
For LaTeX to work, there has to be a newline between like this:
\preformatted{
\end{verbatim}
\end{Section}
}
The problem is that empty lines are stripped (for 'section's only?!?).
A work around seems to add a non-empty line. Try for instance to add
the
following after this 'preformatted' Rd environment at it will
work (as it is now, it will not work!):
\preformatted{
\emph{} % A dummy line to "fool" R CMD check and LaTeX
}
}
-------------------------------------------------------
End Rd example
