isd

Classify changes over time


Description

Classify changes over time using the ISD-system introduced by Galtung (1969).

Usage

isd(V, tolerance=0.1)

Arguments

V

A vector with length 3

tolerance

Specify how similar values have to be to be treated as different (optional). Differences smaller than or equal to the tolerance are ignored.

Details

This function implements the ISD-system introduced by Galtung (1969). The input is a vector of length 3. Each value stands for a different point in time. The ISD-system examines the two transition points, and classifies the changes over time.

Value

The function returns a list. The type returns a number corresponding to the pattern described by Galtung. The description returns a string where the two transitions are spelled out (increase, flat, decrease).
