Hi When I type:> ?nlsI 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
A more accurate wording, I believe, would be "Port Library" see: http://www.bell-labs.com/project/PORT/ Martin will correct me if there really is a package!! Unfortunately, the licensing link is broken on the URL above and it would be interesting to know what the status of licensing really is, since there were/are lots of useful things in this library. url: www.econ.uiuc.edu/~roger Roger Koenker email rkoenker at uiuc.edu Department of Economics vox: 217-333-4558 University of Illinois fax: 217-244-6678 Champaign, IL 61820 On Jul 9, 2008, at 11:42 AM, Jos Kaefer wrote:> Hi > > When I type: >> ?nls > > I come across this section: > > algorithm: character string specifying the algorithm to use.

It is not an R package, but rather a collection of Fortran functions that R uses from netlib: http://www.netlib.org/port/ On Wed, 9 Jul 2008, Jos Kaefer wrote:> Hi > > When I type: > > ?nls > > I come across this section: > > algorithm: character string specifying the algorithm to use.
