[R] weights in nls

[ben@zoo.ufl.edu]

  Does the nls package actually allow for weighted nonlinear regression?
(i.e., I have data with individual variances associated, I'd like to use
1/var to weight the points.)  The "nls" function does have a weights
argument, but it doesn't seem to do anything as far as I can tell ...

  thanks ...
