  Look for an error in your analytic gradient function? :-)
  If that doesn't help, we need a lot more information -- start
by reading the posting guide and then (1) tell us what you're
trying to do, (2) what packages or functions you're using
(I'm guessing nlm, but it might be deeply nested within some
other functions) -- sessionInfo() output is always helpful --
and (3) PROVIDE A REPRODUCIBLE EXAMPLE!
