splitfngr: Combined Evaluation and Split Access of Functions
Some R functions, such as optim(), require a function
its gradient passed as separate arguments. When these are
expensive to calculate it may be much faster to calculate
the function (fn) and gradient (gr) together since they often share
many calculations (chain rule). This package allows the user
to pass in a single function that returns both the function
and gradient, then splits (hence 'splitfngr') them
so the results can be accessed
separately. The functions provided allow this to be done with
any number of functions/values, not just for functions and gradients.
