neighbors | R Documentation |
A vertex is a neighbor of another one (in other words, the two vertices are adjacent), if they are incident to the same edge.
neighbors(graph, v, mode = c("out", "in", "all", "total"))
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. |
A vertex sequence containing the neighbors of the input vertex.
