R help - Jan 2009 - error managment

Hello R experts!
 I'm running a FOR loop in which at every step an arima model is generated.
The problem is some series produces numeric problems with optim. My question
is if there is a way of telling to R that at every critical error of optim
jumps to the next series instead of stopping the calculations. Or better
yet, tell it to run another arima fit but with a different optmization
algorithm.



Thanks!!!
