I find Sweave very useful and I was trying to combine it with the
latex package fancyvrb. I was trying to get line numbering and labels
in order to reference the lines where particular commands occur.
Unfortunately, I haven't been able to figure out how to do it. Maybe
somebody can help me.
The following is a sample Rnw file: the first part shows what I would
like to get, the second what I tried but didn't work.
\documentclass[12pt]{article}
\usepackage{/usr/local/R-2.7.0-inst/share/texmf/Sweave}
\usepackage{fancyvrb}
\DefineVerbatimEnvironment{Rcode}{Verbatim}{%
commentchar=@,
frame=lines, label=\textrm{\bf R code}, numbers=left,
framesep=10pt, fontshape=sl, commandchars=\\\{\}}
\SweaveOpts{keep.source = TRUE}
\begin{document}
I would like to produce something like the following, but using Sweave. Note
the label on line \ref{Rcode:sum}.
\begin{Rcode}
> y <- c(53, 57, 66, 67, 72) # count data
> n <- length(y)
> s <- sum(y) \label{Rcode:sum}
\end{Rcode}
The following naive approach does not work, not either without the label...
\begin{Rcode}
<<>>=
y <- c(53, 57, 66, 67, 72) # count data
n <- length(y)
s <- sum(y) \label{Rcode:sum}
@
\end{Rcode}
\end{document}
Thank you in advance for your suggestions!
