Usage

recursive_last(x, level = 1L, ...)

Arguments

x	An object such as a vector or a list that has '[' or '[[' methods defined for it

Examples

## Define a complicated list where it's second object is a list itself
l2 <- list(j = 21:30, k = list(a = 1:10, b = 11:20))

## Run with defaults
recursive_last(l2)

## Run 2 levels of recursion
recursive_last(l2, level = 2L)

## Change the advanced argument 'selector' to '[['
recursive_last(l2, level = 2L, selector = '[[')

## Go 3 levels deep
recursive_last(l2, level = 3L, selector = '[[')

## Go 2 levels deep using different selectors at each level
recursive_last(l2, level = 2L, selector = c('[', '[['))
