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.
