Hi list,
I was using Sweave and was wondering if anyone has had any luck changing the
font colors of the code chunks. For instance, in my .Rnw preample I tried
including:
===
\usepackage[usenames]{colors}
\definecolor{darkred}{rgb}{0.545,0,0}
\definecolor{midnightblue}{rgb}{0.098,0.098,0.439}
\DefineVerbatimEnvironment{Sinput}{Verbatim}{fontshape=sl,formatcom={\color{midnightblue}}}
\DefineVerbatimEnvironment{Soutput}{Verbatim}{formatcom={\color{darkred}}}
\DefineVerbatimEnvironment{Scode}{Verbatim}{fontshape=sl,formatcom={\color{blue}}}
===
which works in the sense that colors do show up in the processed pdf document,
but extra spaces in between the input and output code chunks appear (which is
not the case when colors are not specified), resulting in a long document with
many blank lines.
Alternatively, in the resulting tex document I replaced all instances of
\begin{Sinput}... \end{Sinput} with {\color{midnightblue}\begin{Sinput} ...
\end{Sinput}} and darkred for Soutput and so on. When I do this, I get the
following error message:
=== LaTeX excerpt ===
\begin{Schunk}
{\color{midnightblue}\begin{Sinput}
> ISOdatetime(1970, 1, 1, 0, 0, 0, "") - ISOdatetime(1970, 1, 1,
+ 0, 0, 0, "GMT")
\end{Sinput}}
{\color{darkred}\begin{Soutput}
Time difference of 8 hours
\end{Soutput}}
\end{Schunk}
===
=== error message ===
)
! FancyVerb Error:
Extraneous input `}\end{}' between \end{Sinput} and line end
.
[EMAIL PROTECTED] ... {FancyVerb Error:
\space \space #1
}
l.13 \end{Sinput}}
===
I guess I don't know enough of the Schunk/Sinput/Soutput definitions to toy
with it and was wondering if anyone had tried something similar.
Thanks!
Stephen
