calcaute beta diversity

Description

calcaute beta diversity

Usage

betadiv(physeq, distance = "bray", method = "PCoA")

Arguments

physeq	A phyloseq object containing merged information of abundance, taxonomic assignment, sample data including the measured variables and categorical information of the samples, and / or phylogenetic tree if available.
distance	A string character specifying dissimilarity index to be used in calculating pairwise distances (Default index is "bray".).
