Re: [R] good numerical optimization to use in R?
Have you tried the maxLik package? If that is not adequate, you can check CRAN Task View: Optimization and Mathematical Programming (http://cran.fhcrc.org/web/views/Optimization.html). Or try the new RSiteSearch.function in the RSiteSearch package. If none of these adequate, please provide another post with more detail about what you've tried and why it does not seem adequate, preferably providing provide commented, minimal, self-contained, reproducible code, as suggeste in the posting guide http://www.R-project.org/posting-guide.html;. Hope this helps. Spencer Michael wrote: Hi all, Could anybody point me to a good/robust numerical optimization program to use in R? I am doing some MLE fitting.

Re: [R] good numerical optimization to use in R?
What kind of optimization problem are you trying to solve? For smooth, nonlinear optimization, with box-constraints - optim(), nlminb(), spg() For smooth, nonlinear optimization, with linear inequality constraints - constrOptim() For smooth, nonlinear optimization, with equality and/or inequality constraints - Rdonlp2 See the CRAN Task View: Optimization and Mathematical Programming for more information.
