Hi
When I type:
> ?nls
I come across this section:
algorithm: character string specifying the algorithm to use. The
default algorithm is a Gauss-Newton algorithm. Other
possible values are '"plinear"' for the Golub-Pereyra
algorithm for partially linear least-squares models and
'"port"' for the 'nl2sol' algorithm from the Port package.
The simple question is: where's the Port package?
I can't find it on cran.
Thanks,
Jos
