match_points_to_graph
Alias for match_points_to_graph
match_points_to_graph(verts, xy, connected = FALSE)
verts |
A |
xy |
coordinates of points to be matched to the vertices, either as
matrix or sf-formatted |
connected |
Should points be matched to the same (largest) connected
component of graph? If |
A vector index into verts
