phylosor.rnd: Null PhyloSor values of phylogenetic beta-diversity

Description

PhyloSor values obtained by randomization for different choices of null models

Usage

phylosor.rnd(samp,tree, cstSor=TRUE, null.model=c("taxa.labels",
    "frequency","richness","independentswap","trialswap"),
    runs=999, iterations=1000)

Arguments

samp

Community data matrix

tree

Object of class phylo

cstSor

TRUE if the Sorensen similarity should be kept constant across communities. FALSE otherwise

null.model

Null model to use (see Details section)

runs

Number of randomizations

iterations

Number of iterations to use for each randomization (for independent swap and trial null models)

Value

• A list of length the number of runs. Each element of the list is a distance matrix containing the PhyloSor values of phylogenetic beta-diversity obtained by randomization

Details

Currently implemented null models (arguments to null.model): [object Object],[object Object],[object Object],[object Object],[object Object]
