Linear decay function

Source: R/decay_linear.R
decay_linear.Rd

Returns a linear weighting function 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_linear(cutoff)

Arguments

cutoff

A numeric vector. Indicates the travel cost cutoffs until which the weighting factor decays linearly. From this point onward the weight is equal to 0.

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).

Examples

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

weighting_function(c(20, 35))

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

weighting_function(c(20, 35))
