[R] Sweave, beamer and alert within code chunks

[Giovanni Petris]

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)) \alert<2>{# V must be positive}
> mleOut$convergence  \alert<3>{# always check this!!!}
[1] 0
\end{semiverbatim}

How can I get a similar effect using Sweave?

Thank you in advance!

Best,
Giovanni Petris
