nlsrob fails with puzzling error message on input accepted by nls
I have a nonlinear model estimation problem with ~50,000 data records
and a simple 3 parameter model (logistic type - please don't tell me
that there are linear methods for such a problem). I run nls with
constraints once to get a good initial parameter guess, then try to run
nlrob to get improved estimates. The model is well-behaved for the
parameters that come from nls - no huge values, NAs
