get.backbone function

get.backbone

This function extracts the backbone of a network

get.backbone(G, alpha, directed = TRUE)

Arguments

• G: igraph network
• alpha: Significance level
• directed: Default is TRUE

Returns

Backbone of the network

Examples

require(igraph)

##Create a random (directed) network
gs<-erdos.renyi.game(50,0.2,directed = TRUE)

##Add edge weights to the network
E(gs)$weight<-runif(ecount(gs), 0, 1)

##Extract backbone at 0.05 significance level
backbone<-get.backbone(gs,0.1)
