Create matrices representing origin-destination coordinates

This function takes a wide range of input data types (spatial lines, points or text strings) and returns a matrix of coordinates representing origin (fx, fy) and destination (tx, ty) points.

Usage

od_coords(from = NULL, to = NULL, l = NULL)

Arguments

from

An object representing origins (if lines are provided as the first argument, from is assigned to l)

to

An object representing destinations

l

Only needed if from and to are empty, in which case this should be a spatial object representing desire lines
