od_coordinates_ids

This function takes a matrix with 4 columns representing origin and destination coordinates
and returns a data frame with 3 columns with the ID of each linestring, plus
the coordinates representing origin and destination coordinates.
Essentially the function is a pivot, converting from wide to long format, to feed
into other functions for creating geographic desire lines.

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.
