Color of exported R code results using LaTeX listings

Color of exported R code results using LaTeX listings

[Steven Delean]

Hi everyone,

I am using org-mode to make a beamer presentation that includes blocks of R code and wish to export the source code and results to pdf in color (using the listings package).

The source code block syntax is highlighted successfully, but the output results of the executed R code are not colored at all. 

The results are presented in \begin{verbatim}...\end{verbatim}, whereas the source code is presented within \begin{lstlisting}...\end{lstlisting}. I can affect changes to the fontsize and color of the source code using \lstset in the .org document header, but not the results output from evaluating the code.

Is there some way I can export these results in color?

Thanks for any suggestions,

Regards,
Steve

PS I have the follwing in my .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"))

Hi

This is not an answer to your question, but rather a question to you:
I added your settings to my .emacs file, and I get fontification in the
pdf output, but no color. Do I need any additional settings to get
coloring of the source code?

Cheers,

Rainer

Hi Rainer,

Yes, you will need to provide arguments to the \lstset listings variable
(i.e. add these arguments to a #+BEAMER_HEADER_EXTRA: line). Below are
the subset of arguments that I am using so far, though greater
customisation is available (see listings.pdf
www.ctan.org/tex-archive/macros/latex/contrib/listings/listings.pdf).

\lstset{
  keywordstyle=\color{blue},
  commentstyle=\color{red},
  stringstyle=\color{green},
  basicstyle=\ttfamily\small,
  columns=fullflexible,
  basewidth={0.5em,0.4em}
}

Cheers,
Steve

See http://www.mail-archive.com/emacs-orgmode-mXXj517/zsQ@public.gmane.org/msg28251.html for
examples of pretty-printed code.

Thanks - that looks really nice. Nice example.

As I said in the other email, that should go to worg.

Instead of
#+begin_LaTeX
#+end_LaTeX

I use

#+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:         }

And it also works.

Cheers,

Rainer

Re: Re: Color of exported R code results using LaTeX listings

[Steven Delean]

Thanks very much Rainer and Sébastien for your comments and information.

However, I am still unable to get color output for the _result_ of
evaluating R code blocks.

#+source: Rcode
#+begin_src R :results output :exports both
  x <- 1:5
  square <- function(x) {
    x^2
  }
  square(x)
#+end_src


## below is the .tex code generated which results in fontified and
colored source code (code within lstlisting), but non-colored results
(within verbatim). 

\lstset{language=R}

Rcode() $\equiv$ 
\begin{lstlisting}
  x <- 1:5
  square <- function(x) {
    x^2
  }
  square(x)
\end{lstlisting}

\begin{verbatim}
 [1]  1  4  9 16 25
\end{verbatim}
 
So the question is how to color the output of text within
\begin{verbatim} ...\end{verbatim} in an exported pdf (just a single
color is fine)?

Thanks for your time,
Steve

You could redefine the verbatim environment with
\renewenvironment{verbatim}[args]{begdef}{enddef}

http://www.personal.ceu.hu/tex/defs.htm
http://en.wikibooks.org/wiki/LaTeX/Customizing_LaTeX

If verbatim is only used for the results, nothing should go wrong.

Rainer

For me, this should be addressed in a more semantic view of the Babel world,
and that's (by coincidence) exactly what I asked to Eric (currently on
holidays, if I read correctly) and Dan, yesterday at 17:16.

See [[http://mid.gmane.org/87zkvhoh18.fsf%40mundaneum.com][{babel} Environment around exported results]].

I am positively sure they will address this feature in a fantastic way, as
always...

Best regards,
  Seb

Absolutely - but that does not help Steven at the moment. But I second
your suggestion and statement.

Now this explains it - thanks a million - works absolutely perfectly.

Could that info be added to worg or even the org manual? It mentions the
listings and color package are mentioned, but not that colors need to be
specified to have colors in the resulting latex / pdf file.

Thanks a lot,

Rainer

Is it still the case?  

If so, can you provide a patch against latest Worg?

Thanks!

Re: Color of exported R code results using LaTeX listings

[Eric Schulte]

Hi Steven,

If your R blocks are outputting actual R code, then you can use the
"code" argument to the :results header argument to have the output
exported as R code under listings instead of within verbatim blocks.
--8<---------------cut here---------------start------------->8---
#+begin_src R :results code 8 #+end_src

#+results:
#+BEGIN_SRC R
8
#+END_SRC
--8<---------------cut here---------------end--------------->8---

Alternately if your output is some other language you could use the
":results latex" header argument and explicitly provide the listings
wrapper yourself.

Hope this Helps -- Eric

Re: Color of exported R code results using LaTeX listings

[Steven Delean]

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

What about if your results block is an Org table, instead of verbatim?

Best regards,
