Usage

## Default S3 method:
memoizedCall(what, ..., envir=parent.frame(), force=FALSE, sources=NULL, dirs=NULL)

Arguments

what

The function to be called, or a character string specifying the name of the function to be called, cf. do.call().

...

Arguments passed to the function.

envir

The environment in which the function is evaluated.

force

If TRUE, any cached results are ignored, otherwise not.

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.
