Convert origin-destination coordinates into geographic desire lines

odc_to_sf(odc, d = NULL, crs = 4326)

Arguments

odc: A matrix containing coordinates representing line start and end points
d: An optional data frame to add to the geometry column
crs: The coordinate reference system of the output, if not known in z. 4326 by default.
