Description

Homoteneity is defined as ‘the mean constancy of the S most constant species, expressed as a fraction, where S is the mean species richness of a type.’

Usage

homoteneity(taxa,clustering)

Arguments

taxa

a data.frame of species abundances with samples as rows and species as columns

clustering

a vector of (integer) class memberships, or an object of class ‘clustering’, class ‘partana’, of class partition

Value

a data.frame of homoteneity values

const, concov

Examples

# NOT RUN {
    data(bryceveg) # returns a data.frame of species in sample plots   
    data(brycesite) # returns a data.frame of site variables
    homoteneity(bryceveg,brycesite$quad) # analysis of species constancy
                                         # by USGS quad location
