Plan a route with local data

This function returns the shortest path between locations in, or near to, segements on a SpatialLinesNetwork.

route_local(sln, from, to, l = NULL, ...)

Arguments

sln	The SpatialLinesNetwork or sfNetwork to use.
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
...	Arguments to pass to sum_network_links
