Adjacency lists
Create adjacency lists from a graph, either for adjacent edges or for neighboring vertices
- Keywords
- graphs
Usage
as_adj_list(graph, mode = c("all", "out", "in", "total"))as_adj_edge_list(graph, mode = c("all", "out", "in", "total"))
Arguments
- 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.
Details
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.
Value
A list of numeric vectors.
