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.

Hi all,
 
 Could anybody point me to a good/robust numerical optimization program
 to use in R?
 
 I am doing some MLE fitting. Thanks!
