Calls a function with memoization — memoizedCall • R.cache

Calls a function with memoization, that is, caches the results to be retrieved if the function is called again with the exact same arguments.

# 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.
sources, dirs: Optional arguments passed to loadCache() and saveCache().

Value

Returns the result of the function call.

Details

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.
