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.
Ravi.
