decay_binary: 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)

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).

Arguments

cutoff

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

Examples

if (FALSE) { # identical(tolower(Sys.getenv("NOT_CRAN")), "true")
weighting_function <- decay_binary(cutoff = 30)

weighting_function(c(20, 35))

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

weighting_function(c(20, 35))
