cut: Dividing a Range Into 3 Intervals

In psolymos/intrval: Relational Operators for Intervals

Dividing a Range Into 3 Intervals

Description

Functions for evaluating if values of vectors are within intervals, or less than or higher than interval endpoints. The c within the brackets refer to cut, a similar function.

Usage

x %[c]% interval
x %[c)% interval
x %(c]% interval
x %(c)% interval

Arguments

x	vector or NULL: the values to be compared to interval endpoints.
interval	vector, 2-column matrix, list, or NULL: the interval end points.

Value

Values of x are compared to interval endpoints a and b (a <= b) (see %[]% for details). The functions return an integer vector taking values -1L (value of x is less than or equal to a, depending on the interval type), 0L (value of x is inside the interval), or 1L (value of x is greater than or equal to b, depending on the interval type).
