incident_edges {igraph}

Incident edges of multiple vertices in a graph

Description

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.
