concov: Constancy-Coverage Table for Ecological Community Data

Description

Produces a table of combined species constancy and importance

Usage

concov(taxa,clustering,digits=1,width=5,typical=TRUE,thresh=10)

Arguments

taxa

a taxon data.frame, samples as rows and species as columns

clustering

(1) an object of class ‘clustering’, class ‘partana’, or class ‘partition’, (2) a vector of integer cluster memberships, (3) a factor vector, or (4) a character vector

digits

the number of digits for the importance value of species

width

controls the formatting of columns

typical

an argument passed to importance to control how mean abundance is calculated

thresh

a theshold parameter to control the suppression of small details in the output. Species must have >= thresh constancy in at least one type to appear in the output table

Value

a data.frame with factors (combined constancy and coverage) as columns

Details

concov calls const and importance and then combines the output in a single table.
