route_local: Plan a route with local data

Description

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

Usage

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

Arguments

sln

The SpatialLinesNetwork to use.

from

Text string or coordinates (a numeric vector of length = 2 representing latitude and longitude) representing a point on Earth.

to

Text string or coordinates (a numeric vector of length = 2 representing latitude and longitude) representing a point on Earth. This represents the destination of the trip.

l

Only needed if from and to are empty, in which case this should be a spatial object representing desire lines
