R help - Dec 2008 - How-To capture and handle errors with R

The following error occurs every now and then by calling a function of wmTSA
package:

Error in `row.names<-.data.frame`(`*tmp*`, value = c("1",
"0")) :
  invalid 'row.names' length

I would greatly appreciate some guidelines about how to catch such an error upon
its occurrence and have it handled by my own routine
rather than letting R stop the currently run script.
I had a look a the R on-line documentation about errors handler and also ran
some provided examples that confused my mind.
The error is in textual form. I do not know whether I have to pass the whole
message to the handler.
When such an exception occurs the execution control is not transferred to my
routine.
I would like to see a working example.

Thank you so much,
Maura
