%description
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.
