I'm looking for an example of a simple R script that impliments a contrained nonlinear function using nlm or optim. I'm not exactly sure how to impliment the constraints within the objective function that is passed to nlm/optim.
obj.func <- function( p ) { x(p) <- unconstrained obj function value if( constraint1 > something ) { obj.func <- x(p) } else { obj.func <- some super huge number } } p <- c(0.1,2.4, 5) nlm( obj.func, p, and a bunch of other arguments ) Any suggestions would be very helpful...
