Adjacency lists — get.adjlist • igraph

get.adjlist() was renamed to as_adj_list() to create a more consistent API.

Usage

get.adjlist(
  graph,
  mode = c("all", "out", "in", "total"),
  loops = c("twice", "once", "ignore"),
  multiple = TRUE
)

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.
loops: Character scalar, one of "ignore" (to omit loops), "twice" (to include loop edges twice) and "once" (to include them once). "twice" is not allowed for directed graphs and will be replaced with "once".
multiple: Logical scalar, set to FALSE to use only one representative of each set of parallel edges.
