Re: Color of exported R code results using LaTeX listings

[Steven Delean <steven.delean@adelaide.edu.au>]

Hi Eric, Rainer and Sébastien,

Thanks again for all your assistance. I was not able to achieve the
results I was after exactly using any proposed solutions, but have found
a way forward and outline my solution below in case it benefits others.

The following allows fontification and syntax highlighting for source
code and a single color for exported output, and works both for latex
documents and beamer slides. 
NB: A single color for source code in exported documents can be acheived
by adding e.g. \color{blue} to basicstyle.

1. The following must appear in your .emacs
(require 'org-latex)
(setq org-export-latex-listings t)
(add-to-list 'org-export-latex-packages-alist '("" "listings"))
(add-to-list 'org-export-latex-packages-alist '("" "color"))

2. Add the following to your .org document header to allow colors and
'nice' font
#+LATEX_HEADER: \lstset{
#+LATEX_HEADER:         keywordstyle=\color{blue},
#+LATEX_HEADER:         commentstyle=\color{red},
#+LATEX_HEADER:         stringstyle=\color{green},
#+LATEX_HEADER:         basicstyle=\ttfamily\small,
#+LATEX_HEADER:         columns=fullflexible,
#+LATEX_HEADER:         basewidth={0.5em,0.4em}
#+LATEX_HEADER:         }

3. Also add the following to your .org document header to allow the
output results of evaluating R (or other language) code to be in color
#+LATEX_HEADER: \RequirePackage{fancyvrb}
#+LATEX_HEADER: \DefineVerbatimEnvironment{verbatim}{Verbatim}{fontsize=
\small,formatcom = {\color[rgb]{0.5,0,0}}}

Hope it helps,
Regards,
Steve
