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 :) Thanks Paul -- View this message in context: http://r.789695.n4.nabble.com/How-to-say-if-error-tp2266619p2266619.html Sent from the R help mailing list archive at Nabble.com.
