as_adj_list

Adjacency lists

Create adjacency lists from a graph, either for adjacent edges or for neighboring vertices

as_adj_list(graph, mode = c("all", "out", "in", "total"))

as_adj_edge_list(graph, mode = c("all", "out", "in", "total"))

`graph`	The input graph.
`mode`	Character scalar, it gives what kind of adjacent edges/vertices to include in the lists. ‘`out`’ is for outgoing edges/vertices, ‘`in`’ is for incoming edges/vertices, ‘`all`’ is for both. This argument is ignored for undirected graphs.

as_adj_list returns a list of numeric vectors, which include the ids of neighbor vertices (according to the mode argument) of all vertices.

as_adj_edge_list returns a list of numeric vectors, which include the ids of adjacent edgs (according to the mode argument) of all vertices.

A list of numeric vectors.

g <- make_ring(10)
