From igraph v1.2.3

##### Incident edges of multiple vertices in a graph

This function is similar to `incident`

, but it
queries multiple vertices at once.

##### Usage

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

##### Arguments

- 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.

##### Value

A list of edge sequences.
