null.models {NST}

Options of null model algorithms

Description

The parameters passing to function taxo.null for each null model algorithm

Usage

data("null.models")

Format

sp.freq

character, how the species occurrence frequency will be constrainted in the null model.

samp.rich

character, how the species richness in each sample will be constrainted in the null model.

swap.method
