#Case matters!
x*X

The following code does not compile as there are errors but it does not show the error. It would be nice if I was able to display the errors in sweave.

Answer 1

s Shane suggests, use

<<echo=TRUE,eval=FALSE>> 

for the code that will error, but you want to display, and then again with

<<echo=FALSE,eval=TRUE,results=verbatim>> 

but with the same code wrapped in a try.
