Webhave a computable finite value of fn. (Except for method "L-BFGS-B"where the values should always be finite.) optimcan be used recursively, and for a single parameter as well as many. It also accepts a zero-length par, and just evaluates the function with that argument. The controlargument is a list that can supply any of the following components:
