stplanr (version 0.5.1)

route: Plan routes on the transport network

Description

Takes origins and destinations, finds the optimal routes between them and returns the result as a spatial (sf or sp) object. The definition of optimal depends on the routing function used

Usage

route(
  from = NULL,
  to = NULL,
  l = NULL,
  route_fun = stplanr::route_cyclestreets,
  n_print = 10,
  list_output = FALSE,
  ...
)

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

route_fun

A routing function to be used for converting the straight lines to routes od2line()

n_print

A number specifying how frequently progress updates should be shown

list_output

If FALSE (default) assumes spatial (linestring) object output. Set to TRUE to save output as a list.

...

Arguments passed to the routing function, e.g. route_cyclestreets()
