Syntax highlighting is easy with the highlight package, on which the
knitr package is based, e.g.
- sample source: https://gist.github.com/1803930
- sample pdf: https://github.com/downloads/yihui/knitr/knitr-beamer.pdf
It is possible to insert \alert{} with knitr, but you have to provide
the logic: where do you want to insert them? use \alert{} on all
comments?
Anyway, here is a demo:
- source: https://gist.github.com/2629886#file_knitr_alert.rnw
- output: https://github.com/downloads/yihui/knitr/knitr-alert.pdf
The knitr hooks allows you to wrestle with R code and output in any
way you want, and you may need one hour or two learning the design.
BTW, I'm not sure if it is my problem or yours -- your code does not
actually run under my R 2.15.0. Long live the reproducible research!

Hi all,
Using Beamer, in order to highlight a piece of R code I do something
like this - note the \structure and \alert commands:
\begin{semiverbatim}
mleOut - \structure{dlmMLE}(Nile,
+ parm = c(0.2, 120), # initial values for optimizer
+ lower = c(1e-7, 0)) \alert2{# V must be positive}
mleOut$convergence \alert3{# always check this!!!}
[1] 0
\end{semiverbatim}
How can I get a similar effect using Sweave?
Thank you in advance!
Best,
Giovanni Petris
