Neighboring (adjacent) vertices in a graph

A vertex is a neighbor of another one (in other words, the two vertices are adjacent), if they are incident to the same edge.

Usage
neighbors(graph, v, mode = c("out", "in", "all", "total"))
Arguments
graph
The input graph.
v
The vertex of which the adjacent vertices are queried.
mode
Whether to query outgoing (out), incoming (in) edges, or both types (all). This is ignored for undirected graphs.
Value

  • A vertex sequence containing the neighbors of the input vertex.
