Usage

pluck_depth(x, is_node = NULL)

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.

Value

An integer.

  list(list()),
  list(list(list(1)))
)
pluck_depth(x)
