I use pgfSweave so that I can embed R code and output in LaTeX;
pgfSweave depends on the formatR package to format the code, and the highlight
package to highlight R code; graphics are based on tikzDevice, which has better quality than R's PDF or postscript output, in my opinion.

Subject: [R] R-latex syntax highlighting?

Hello,

Can anyone provide or point me to a good setup for the listings latex package that would produce nice R-syntax highlighting?

I am using an example I found in internet for setting up listings like this:
\lstset{
language=R,
basicstyle=\scriptsize\ttfamily,
commentstyle=\ttfamily\color{gray},
numbers=left,
numberstyle=\ttfamily\color{red}\footnotesize,
stepnumber=1,
numbersep=5pt,
backgroundcolor=\color{white},
showspaces=false,
showstringspaces=false,
showtabs=false,
frame=single,
tabsize=2,
captionpos=b,
breaklines=true,
breakatwhitespace=false,
title=\lstname,
escapeinside={},
keywordstyle={},
morekeywords={}
}

But I know that using the color latex package it can look a lot nicer and I guess some people might have configured that before and are willing to share it?

I'm also interested in the a similar problem best way to put R code with syntax highlighting into a presentation. I use Apple's Keynote. 

Many thanks in advance,
Best regards,
Giovanni
