[R-sig-ME] Fwd: Re: R-core post from jw1085 at wildcats.unh.edu requires approval

Somebody might be able to look at your error message and figure out what is
wrong, but often that is not possible just by looking.  If you want people
to help you, then you need to help people understand your problem, perhaps
using simulated data.  See:
