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.
