Adjacent vertices of multiple vertices in a graph
This function is similar to neighbors, but it queries
the adjacent vertices for multiple vertices at once.
adjacent_vertices(graph, v, mode = c("out", "in", "all", "total"))graph |
Input graph. |
v |
The vertices to query. |
mode |
Whether to query outgoing (‘out’), incoming (‘in’) edges, or both types (‘all’). This is ignored for undirected graphs. |
A list of vertex sequences.
