Diversity Test

Description

Compares Shannon diversity between samples.

Usage

test_diversity(object, ...)

## S4 method for signature 'matrix'
test_diversity(object, adjust = "holm", ...)

## S4 method for signature 'data.frame'
test_diversity(object, adjust = "holm", ...)

Arguments

object	A m \times p numeric matrix or data.frame of count data (absolute frequencies giving the number of individuals for each category, i.e. a contingency table). A data.frame will be coerced to a numeric matrix via data.matrix().
...	Further arguments to be passed to internal methods.
adjust	A character string specifying the method for adjusting p values (see stats::p.adjust()).

Details

This test produces two sided pairwise comparisons: it returns a matrix of adjusted p values.

Value

A numeric matrix.
