pn_index function

PN Centrality Index

centrality index for signed networks by Everett and Borgatti

pn_index(g, mode = c("all", "in", "out"))

Arguments

• g: igraph object with a sign edge attribute.
• mode: character string, “out” for out-pn, “in” for in-pn or “all” for undirected networks.

Returns

centrality scores as numeric vector.

Examples

A <- matrix(c(
    0, 1, 0, 1, 0, 0, 0, -1, -1, 0,
    1, 0, 1, -1, 1, -1, -1, 0, 0, 0,
    0, 1, 0, 1, -1, 0, 0, 0, -1, 0,
    1, -1, 1, 0, 1, -1, -1, 0, 0, 0,
    0, 1, -1, 1, 0, 1, 0, -1, 0, -1,
    0, -1, 0, -1, 1, 0, 1, 0, 1, -1,
    0, -1, 0, -1, 0, 1, 0, 1, -1, 1,
    -1, 0, 0, 0, -1, 0, 1, 0, 1, 0,
    -1, 0, -1, 0, 0, 1, -1, 1, 0, 1,
    0, 0, 0, 0, -1, -1, 1, 0, 1, 0
), 10, 10)
g <- graph_from_adjacency_matrix_signed(A,"undirected")
pn_index(g)
