core_periphery_weighted function

Core-Periphery for Weighted Networks

This function implements rich club core-periphery algorithm (Ma & Mondragón, 2015) to identify members of the core and periphery in weighted networks

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

Returns

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")
