igraph (version 1.0.0)

adjacent_vertices: Adjacent vertices of multiple vertices in a graph

Description

This function is similar to neighbors, but it queries the adjacent vertices for multiple vertices at once.

Usage

adjacent_vertices(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 vertex sequences.
