cutter

Function to Identify in Which Interval a Value Falls

Description

Function to identify in which interval of a set of cut points, cuts, a value x falls within or beyond. The number of intervals is equal to the number of cut points plus 1. Values of x have to exceed the value of the cut point to be allocated to the higher interval.

Usage

cutter(x, cuts)

Arguments

`x`	name of the vector to be processed.
`cuts`	the vector of cut points.

Value

`xi`	a vector of the same length as `x` containing an integer between 1 and the number of cut points plus 1 indicating in which interval each value of `x` fell. Values `<`cut[1] have `xi` set to 1, and values `>`cut[highest] have `xi` set to the number of cut points plus 1.
