Select vertices on graph that are closest to the specified coordinates.

Select vertices on graph that are closest to the specified coordinates.

select_vertices_by_coordinates(graph, start_coords, end_coords)

Arguments

graph	data.frame containing the street network.
start_coords	numeric coordinates of the start point.
end_coords	numeric coordinates of the end point.

Value

list containing the two rows of the input data.frame that are closest to the start and end coordinates

Examples

not_run({
  road <- road_data_sample
  start_pt <- c (11.603, 48.163)
  end_pt <- c (11.608, 48.167)
  pts <- select_vertices_by_coordinates (graph = road, start_coords = start_pt,
                                         end_coords = end_pt)
})
