Description

Input OD-table with Origins, Destinations, Population, Jobs, Catchment binary identification, and a pre-calculated impedance function f

Usage

sp_avail(x, o_id, d_id, pop, opp, r, f, alpha = 1)

Arguments

x	A data frame with origin-destination information, including identifiers for origins, destinations, population, opportunities, and a pre-calculated impedance function
o_id	The name of the column in data frame x that contains the unique origin identifiers
d_id	The name of the column in data frame x that contains the unique destination identifiers
pop	The name of the column in data frame x that contains the population
opp	The name of the column in data frame x that contains the opportunities
r	The name of the column in data frame x that contains catchment restrictions, or a column of 1s if there are none
f	The name of the column in data frame x that contains the values of the impedance function
alpha	A number string with the name of the column in data frame x that contains the values of the impedance function

Value

A vector with the number of opportunities available to o_id from d_id
