Re: [Rd] nlminb: names of parameter vector not passed to objective function (fixed)

2008-12-07 Thread Thomas Petzoldt
NEWS, rev. 47094 now says: o nlminb() copies names from 'start' to the parameter vector used (for consistency with optim()). Dear Prof. Ripley, thank you very much for doing this. Thomas Petzoldt __ R-devel@r-project.org mailing list

Dear Prof. Ripley, thank you very much for the fast response. I am very grateful for all the work that the R Core does and so I try to contribute my humble part as a tester. Prof Brian Ripley wrote: On Wed, 3 Dec 2008, Thomas Petzoldt wrote: Dear R developers, I tried to use nlminb instea

Dear R developers, I tried to use nlminb instead of optim for a current problem (fitting parameters of a differential equation model). The PORT algorithm converged much better than any of optim's methods and the identified parameters are plausible. However, it took me a while before spotting
