Hi, Is there a "R" function that uses the Gauss-Newton method to minimize a nonlinear regression model. I mean in the same manner as the "nlsfit" Splus function, where you can specify the model and the derivatives. regards ahmed. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)

Hmm. In my version of S-Plus (4.5), there is no function nlsfit() available. You might want to take a look in the package "nls".
