od_coordinates

This function takes an 'od data frame' with the first
two columns matching IDs of spatial objects, and
matches them with objects representing origins and destinations
in wide range of input data types (spatial lines, points or text strings).
It returns a data frame of coordinates representing movement between all origin (ox, oy) and destination (dx, dy) points.

The aim of 'od' is to provide tools and example datasets for
working with origin-destination ('OD') datasets of the type used to
describe aggregate urban mobility patterns (Carey et al. 1981)
<doi:10.1287/trsc.15.1.32>. The package builds on functions for
working with 'OD' data in the package 'stplanr', (Lovelace and Ellison
2018) <doi:10.32614/RJ-2018-053> with a focus on computational
efficiency and support for the 'sf' class system (Pebesma 2018)
<doi:10.32614/RJ-2018-009>. With few dependencies and a simple class
system based on data frames, the package is intended to facilitate
efficient analysis of 'OD' datasets and to provide a place for
developing new functions. The package enables the creation and
analysis of geographic entities representing large scale mobility
patterns, from daily travel between zones in cities to migration
between countries.
