PN Centrality Index

centrality index for signed networks by Everett and Borgatti

Usage

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.

Value

centrality scores as numeric vector.
