g_percol: Prune a graph using the 'percolation threshold' method

In graph4lg: Build Graphs for Landscape Genetics Analysis

Prune a graph using the 'percolation threshold' method

Description

The function allows to prune a graph by removing the links with the largest weights until the graph breaks into two components. The returned graph is the last graph with only one component.

Usage

g_percol(x, val_step = 20)

Arguments

x	A symmetric matrix or a dist object with pairwise distances between nodes
val_step	The number of classes to create to search for the threshold value without testing all the possibilities. By default, 'val_step = 20'.

Value

A graph object of type igraph

data(data_ex_genind)
suppressWarnings(mat_w <- graph4lg::mat_geo_dist(data = pts_pop_ex,
                            ID = "ID",
                            x = "x",
                            y = "y"))
g_percol(x = mat_w)
