WeboptimHessis an auxiliary function to compute the Hessian at a later stage if hessian = TRUEwas forgotten. The default method is an implementation of that of Nelder and Mead (1965), that uses only function values and is robust but relatively slow. It will work reasonably well for non-differentiable functions.
