Hi - I am looping over a structural equation model for a variety of datasets. Occasionally, the model returns an error and the loop then breaks. I'd like to set a condition which says something like "if error, then print NAs" rather than the loop breaking, but I don't know how to say "if error".

I'm sure there's a simple answer; I've tried searching Nabble, but error as a hitword comes up rather often on Nabble lists :)
