InteractionStrength: Interaction strength of a pairwise interaction

In DavidGarciaCallejas/DGC: David Garcia-Callejas' functions

Description

Interaction strength calculated as the sign of the interaction multiplied by a scaling factor

Usage

InteractionStrength(n1, n2, sign.matrix, sp1, sp2, scale.factor)

Arguments

n1	Abundance of the first species
n2	Abundance of the second species
sign.matrix	sign matrix of the community
sp1	index of the first species in the sign matrix
sp2	index of the second species in the sign matrix
scale.factor	numeric vector with five elements, giving the maximum strength relative to species' intrinsic growth rate. If e.g. the scale factor equals 1, a certain interaction can have a strength of the same order of magnitude that the r parameter

Value

dimensionless interaction strength value

Examples

InteractionStrength(n1 = 10,n2 = 100,
sign.matrix = matrix(data = c(0,-1,1,0),nrow = 2),sp1 = 1,sp2 = 2,scale.factor = rep(0.1,5))
