Ok, folks, I just pushed to git an extension of the nadarwat() function.

The third argument is now optional: if present, it works just like before. If absent or zero, the bandwidth is automatically calculated as suggested by Andreď in his message a few weeks back:

A fourth optional parameter is a Boolean flag to force the leave-one-out estimator.
Thanks Jack. You had proposed to replace the nadarwat_trim setting by a function argument. Any reason why you didn't do that here?

cheers,
