Reverse Code a Numeric Vector

Description

reverse reverse codes a numeric vector based on minimum and maximum values. For example, say numerical values of response options can range from 1 to 4. The function will change 1 to 4, 2 to 3, 3 to 2, and 4 to 1. If there are an odd number of response options, the middle in the sequence will be unchanged.

Usage

reverse(x, mini, maxi)

Arguments

x	numeric vector.
mini	numeric vector of length 1 specifying the minimum numeric value.
maxi	numeric vector of length 1 specifying the maximum numeric value.

Value

numeric vector that correlates exactly -1 with x.
