Hej Martin!

I’d like to have multi-line comments in my vignette and the easiest way I know 
is to use the “comment” environment from the verbatim package - i.e. 
\begin{comment}…\end{comment}. However, when I do this, i.e. load the verbatim 
package after having “sourced” the BiocStyle package, generating the pdf just 
fails without any error message.

Here’s a tiny .Rnw example of how to reproduce the error:

\documentclass[11pt,a4paper]{article}
% Bioc style
<<style, eval=TRUE, echo=FALSE, results=tex>>=
BiocStyle::latex()
@
\usepackage{verbatim}
\begin{document}
Some text
\begin{comment}
some comments not to be seen by the user
\end{comment}
Some more text
\end{document}

The generated pdf stops after the text “Some text”. I tried to track it down, 
but I’m out of my depth in latex style file. Do you have any idea what is 
happening? And do you have any suggestion of how I could go around this other 
than using % on every comment line?


If I take your file and

  R CMD Sweave Nico.Rnw
  pdflatex Nico.tex

I get

! Undefined control sequence.
\f@ncyolh ->\thetitle
                      \strut
l.15 \end{document}

?

which is because the vignette needs to have a title, e.g., in the preamble

\usepackage{verbatim}
\title{My amazing document}
\begin{document}

If I add this, then things seem to work fine.

The undefined control sequence doesn't sound like what you saw, so maybe more details are needed? I'm using

$ R --vanilla --slave -e "R.version.string"
[1] "R Under development (unstable) (2013-12-01 r64371)"

$ pdflatex --version
pdfTeX 3.1415926-1.40.10-2.2 (TeX Live 2009/Debian)

Cheers,
