coords_to_od | R Documentation |
Takes geographic coordinates and converts them into a data frame representing the potential flows, or 'spatial interaction', between every combination of points.
coords_to_od(p, interzone_only = FALSE, ids_only = FALSE)
p |
A spatial points object or a matrix of coordinates representing points |
interzone_only |
Should the result only include interzonal OD pairs, in
which the ID of the origin is different from the ID of the destination
zone? |
ids_only |
Should a data frame with only 2 columns (origin and
destination IDs) be returned? The default is |
A data frame object with O and D codes and origin and destination coordinates.
p = sf::st_coordinates(od_data_centroids[1:3, ])
od = points_to_od(p)
(od = coords_to_od(p, interzone_only = TRUE))
l = odc_to_sf(od[3:6], d = od[1:2])
l$v = 1
(l_oneway = od_oneway(l))
plot(l_oneway)
