dupNodes (version 0.3.0)

betweenness.with.duplicated.nodes: Computes betweenness of an igraph object that already has duplicated nodes

Description

This is an implementation of the method published in the paper "Intra-family links in the analysis of marital networks" mm24:intra_family_linksdupNodes, which proposed a duplication of nodes that includes self-loops to get a reflect better (and include all information about) the status of all nodes in the network, computing betweenness ignoring the duplicated nodes.

Usage

betweenness.with.duplicated.nodes(dup.graph)

Value

A list with betweenness values indexed by node name.

Arguments

dup.graph

A graph object that has already duplicated nodes with self-loops. Essentially, it will recognize duplicated nodes as those with a prime at the end. Will not return betweenness value for these (it will be exactly the same as the other one).

Details

This method computes betweenness centrality in the regular way for the graph that includes duplicated nodes; it will only return values for the "original" nodes, however.

This object should be created with the function dup.nodes.from.data.frame or dup.nodes.from.graph

Examples

library(igraph)
V1 <- c("A", "A","B","C","D","E")
V2 <- c("A", "B","C","D","E","A")
df <- data.frame(V1, V2)

dup.graph <- dup.nodes.from.data.frame(df)
print(betweenness.with.duplicated.nodes(dup.graph))
