pluck_depth: Compute the depth of a vector

Description

The depth of a vector is how many levels that you can index/pluck into it. pluck_depth() was previously called vec_depth().

Usage

pluck_depth(x, is_node = NULL)

Value

An integer.

Arguments

x

A vector

is_node

Optionally override the default criteria for determine an element can be recursed within. The default matches the behaviour of pluck() which can recurse into lists and expressions.

Examples

x <- list(
  list(),
  list(list()),
  list(list(list(1)))
)
pluck_depth(x)
x |> map_int(pluck_depth)
