kv: Key value iteration

In decisionpatterns/r-hash: A Hash/Dictionary/Map/Associated Array for R

Description

Create a list with k and v elements that is useful for explicit iteration

Usage

kv(x, ...)

## S3 method for class 'hash'
kv(x, ...)

Arguments

x	object such as vector or list to separate into key value pairs
...	additional arguments

Details

No magic here, just something simple to convert x into a list of lists. Each element of x is broken into a list with elements k (key) and v (value). See examples.

For many cases, key-value iteration can be done with *apply or paste functions. This is made to be explicit and work on a variery of objects.

Value

A named list of list; each element of x becomes a one element list with elements k and v representing the keys and values
