Hello, I am trying to port an S-PLUS function to R and have run into some difficulties. Specifically, my S-PLUS function calls nlminb (nonlinear minimization subject to boundary constraints). I have yet to find a similar function in R. Have I missed something? Or has anyone translated the S-PLUS function? Many thanks for any and all help.
