updateFoldRight: Helper for creating function argument to rightward list...

In vreuter/SwissR: Swiss aRmy Knife: R Utilities

Description

Working directly with base::Reduce can be a little tricky, so this function aims to simplify using it. It's intended to be partially applied with something like: pryr::partial(updateFoldRight, f=identity) and then passed as the function argument to foldRightList.

Usage

updateFoldRight(result, newArg, f)

Arguments

result	The growing collection of a Reduce operation in which the "reduction" is actually list formation.
newArg	The new argument being processed.
f	The function to apply to the new argument to generate a new element for result.

See Also

foldRightList for the intended destination of a partially-applied version of this, Reduce for what's wrapped.
