Incident edges of a vertex in a graph

`incident(graph, v, mode = c("all", "out", "in", "total"))`

graph

The input graph.

v

The vertex of which the indicent 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.
