Calls a function with memoization, that is, caches the results to be retrieved if the function is called again with the exact same arguments.
# S3 method for default
memoizedCall(what, ..., envir=parent.frame(), force=FALSE, sources=NULL, dirs=NULL)Arguments passed to the function.
The environment in which the function is evaluated.
If TRUE, any cached results are ignored, otherwise not.
Returns the result of the function call.
If the function returns NULL, that particular function call is
not memoized.
Internally, loadCache() is used to load memoized results,
if available. If not available, then do.call() is used to
evaluate the function call,
and saveCache() is used to save the results to cache.
