graph_from_edgelist_signed(el, signs, directed = FALSE)
Arguments
- el
The edgelist, a two column matrix, character or numeric.
- signs
vector indicating the sign of edges. Entries must be 1 or -1.
- directed
whether to create a directed graph.
Value
a signed network as igraph object
Examples
el <- matrix(c("foo", "bar", "bar", "foobar"), ncol = 2, byrow = TRUE)
signs <- c(-1, 1)
graph_from_edgelist_signed(el, signs)
#> IGRAPH b282804 UN-- 3 2 --
#> + attr: name (v/c), sign (e/n)
#> + edges from b282804 (vertex names):
#> [1] foo--bar bar--foobar
