In ropensci/stplanr: Sustainable Transport Planning

Create matrices representing origin-destination coordinates

Description

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

Examples

od_coords(from = c(0, 52), to = c(1, 53)) # lon/lat coordinates
od_coords(cents_sf[1:3, ], cents_sf[2:4, ]) # sf points
# od_coords("Hereford", "Leeds") # geocode locations
od_coords(flowlines_sf[1:3, ])
