[R-SIG-Finance] Skipping non-convergent GARCH run within a loop

[Anatoly Schmidt]

I'm wondering if there is an option to skip a non-convergent combo of garch
input parameters within the loop upon different parameter values.
I thought something like
if(convergence(ugarchfit(GARCHspec, solver="hybrid", returns)) != "0") {
      print("NA")
      next
}
It did not give an error for the runs with 'good' parameters. But in case
of a 'bad' parameter combo, I got the following:

error in evaluating the argument 'object' in selecting a method for
function 'convergence': object 'B' not found

Thanks much, Alec
