glmPred: calculation of stability using a generalized linear model.

In betaStability: Quantify the Compositional Stability of Each Community Based on a Single Sampling Event

calculation of stability using a generalized linear model.

Description

This function will take the dissimilarity matrix and the environmental matrix as input, and calculate the stability of each site using a generalized linear model (gLM), where the contributions are constrained as non-negative lower.limits=0 to ensure the explainability of each coefficient. The stability is calculated by comparing the predicted distance (based on the linear model) and the mean measured distance (based on vegdist function).

Usage

glmPred(comdist, envmeta, sitenames = NULL)

Arguments

comdist	The community dissimilarity matrix
envmeta	The environmental metadata table/matrix
sitenames	The names of the site

Value

a column vector of predicted stability values for each site

Examples

library(vegan)
data(varespec)
data(varechem)
example.comdist <- vegdist(varespec)
example.stability_GLM <- glmPred(example.comdist, varechem)
