Incident edges of a vertex in a graph
incident(graph, v, mode = c("all", "out", "in", "total"))
graph |

v |
The vertex of which the incident edges are queried. |
mode |
Whether to query outgoing (‘out’), incoming (‘in’) edges, or both types (‘all’). This is ignored for undirected graphs. |
An edge sequence containing the incident edges of the input vertex.
