dupNodes is the companion package to paper “Intra-family links in the analysis of marital networks”, with reference here.

It creates duplicates of nodes that have self loops in undirected graphs such as the one here

A with self loop
A with self loop

in this way

Duplicated node
Duplicated node

which has exactly the same degree; in this way, the weights of these self-loops can be taken into account when computing centrality measures such as betweenness.
