BuildMPN: Build a Minimum Potential Niche Model Network

In esander91/PredictImportance: Generate Networks, Simulate Abundance Data, and Analyze Importance Correlates

Description

Generates a random network of a given size and approximate connectance according to the minimum potential niche model.

Usage

BuildMPN(S = 50, C = 0.1, GapProb = 0.25)

Arguments

S	Number of species in network; defaults to 50
C	Network connectance, defined as 2L/(S(S-1)), where L is the number of links. Defaults to .1. The resulting matrix will have a connectance of C +/- 2sqrt(.5C(1-C)S(S-1)).
GapProb	Probability of a gap in a feeding niche; defaults to .25.

Value

M A weakly connected, unsigned adjacency matrix of size (S,S).
