decay_binaryR Documentation

Binary (a.k.a. step) decay function

Description

Returns a binary weighting function (frequently used to calculate cumulative opportunities measures) to be used inside accessibility calculating functions.

This function is generic over any kind of numeric travel cost, such as distance, time and money.

Usage

decay_binary(cutoff)

Arguments

cutoff

A numeric vector. The numbers indicating the travel cost cutoffs.

Value

A function that takes a generic travel cost vector (numeric) as an input and returns a list of weight vectors (a list of numeric vectors, named after the arguments passed to the decay function).

Other decay functions: decay_exponential(), decay_linear(), decay_logistic(), decay_power(), decay_stepped()

Examples


weighting_function <- decay_binary(cutoff = 30)

weighting_function(c(20, 35))

weighting_function <- decay_binary(cutoff = c(30, 45))

weighting_function(c(20, 35))
