symmetrise_w: Symmetrise_w

In bipartite: Visualising Bipartite Networks and Calculating Some (Ecological) Indices

Symmetrise_w

Description

The symmetrise_w-function creates an undirected one-mode network from a directed one-mode network.

Usage

symmetrise_w(net, method="MAX")

Arguments

net

A one-mode network

method

the method used to decide the weight of the undirected edge. It can be: "MAX" sets the weight to the maximum of the weight(s) of the arc(s) "MIN" sets the weight to the minimumof the weight(s) of the arc(s) "AMEAN" sets the weight to the average (arithmetic mean) of the weight(s) of the arc(s) "SUM" sets the weight to the sum of the weight(s) of the arc(s) "PROD" sets the weight to the product of the weight(s) of the arc(s) "DIFF" sets the weight to the absolute difference between the weight(s) of the arc(s)

Value

Returns the undirected network
