Dear friends,

I am trying to find out the best mixed-effects model for about 200 groups of
data, respectively . I ended up with using a loop to do the modeling
automatically. It will produce the the fitted summary of the candidate
models, as well as some graphs, which can help me to pick the "best" one.
However, sometimes, though not often, the script stops because of error
(mainly convergence problems). This makes the automation less meaningful
So, my question is:

Are we able to force Splus program not to be stopped by the error, in case
the error will not affect the rest of the computation?

Many thanks.
Wei Wang
