cachedCall: Make a cached function call

In alekrutkowski/cacheflow: Simple cached workflow with diagram

Description

This function wrapper both returns a CachedResult and can absorb previous CachedResult(s) as arguments to the wrapped function.

Usage

cachedCall(..fun.., ...)

Arguments

..fun..	The wrapped function whose return value is to be cached. This should be a pure (side-effects free) function that always returns the same result value given the same arguments i.e. should be idempotent (see https://en.wikipedia.org/wiki/Pure_function) such as e.g. algebraic functions mean or sum.
...	Arguments to be passed to ..fun... These can be normal R objects or the results of the previous cachedCall steps.

Value

CachedResult S3 object whose value can be extracted with function extractVal. A CachedResult needs to be wrapped by extractVal if it is used outside cachedCall as an argument in other functions.
