Dear R-helpers,
sorry if this is obvious, but I can't find this in the documentation.
I am using Sweave, and have some code that does not actually work - but I
want to include it anyway, including the error message that R produces.
But on running Sweave() on my .Rnw file, it simply halts when it gets to the
code chunk with the bad code.
I can use \verbatim{} instead, but then I don't get R's output
automatically
(nor do I get the nice syntax highlighting from the highlight package that I
am using).
thanks for your help,
Remko

I think there are intentions to provide more support, but for now it's not there. The way I've done it is like this: \begin{Schunk} \begin{Sinput} > t(Y) + X \end{Sinput} \begin{Soutput} Error in t(Y) + X : non-conformable arrays \end{Soutput} \end{Schunk} This is similar to what Sweave would have produced if it displayed errors without stopping, so it might work properly with your syntax highlighting. If not, another alternative is to use a combination of chunks with eval=false at first to be displayed, then with try() and echo=false to do the actual calculation and display of the error.
