core_periphery_weighted {ITNr} | R Documentation |
Core-Periphery for Weighted Networks
Description
This function implements rich club core-periphery algorithm (Ma & Mondragón, 2015) to identify members of the core and periphery in weighted networks
Usage
core_periphery_weighted(gs, type)
Arguments
gs |
International Trade Network - igraph object. Note for networks not produced using ITNr there needs to be a vertex attribute "name" and edge attribute "weight" |
type |
directed/undirected |
Value
List - 1.)igraph object with core-periphery results added as a node attribute. 2.) Dataframe of core-periphery results.

Examples
require(igraph)
##Create random International Trade Network (igraph object)
ITN<-erdos.renyi.game(50,0.05,directed = TRUE)
##Add edge weights
E(ITN)$weight<-runif(ecount(ITN), 0, 1)
##Add vertex names
V(ITN)$name<-1:vcount(ITN)
##Implement core-periphery algorithm
ITNcp<-core_periphery_weighted(ITN,"directed")
