projecting_tm {tnet}

Projecting binary and weighted two-mode networks onto weighted one-mode networks.

Description

This function is the implemtation of the procedure outlined on
http://toreopsahl.com/2009/05/01/projecting-two-mode-networks-onto-weighted-one-mode-networks/

Usage

projecting_tm(net, method = "sum")

Arguments

net

A two-mode edgelist

method

The method-switch control the method used to calculate the weights.
binary sets all weights to 1
sum sets the weights to the number of cooccurances
Newman bases the weights on Newman's (2001) method of discounting for the size of collaborations.

Value

Returns a one-mode network

Note

version 1.0.0
