Find the index of value nearest to a target value

Description

Usage

which_nearest(values, target, dir)

Arguments

values	numeric vector, the values considered.
target	single numeric value, the target to find the value closest to.
dir	single numeric value. If 0 (the default), finds the index of the value closest to the target, regardless of the direction. If ⁠< 0⁠ or ⁠> 0⁠, finds the index of the value closest to the target, but only considers values at or below/above target, respectfully, if any (otherwise returns the closest value regardless of direction).
