od_coordinates {od}

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 data frame of coordinates representing origin (ox, oy) and destination (dx, dy) points.

Usage

od_coordinates(x, p = NULL, pd = NULL, silent = TRUE, sfnames = FALSE)

Arguments

x

A data frame in which the first two columns are codes representing points/zones of origin and destination

p

Points representing origins and destinations

pd

Points representing destinations, if different from origin points

silent

Hide messages? FALSE by default.

sfnames

Should output column names be compatible with the sf package?

Value

A data frame with origin and destination coordinates

Examples

x = od_data_df
p = od_data_centroids
res = od_coordinates(x, p)[1:2, ]
class(res)
res
od_coordinates(x, p, sfnames = TRUE)[1:2, ]
od_coordinates(x, p, silent = FALSE)[1:2, ]
od_coordinates(x, p)
x = od_data_df2[1:3, ]
p = od_data_centroids2
pd = od_data_destinations
od_coordinates(x, p, pd)
