Diversity Test

Compares Shannon diversity between samples.

Usage

test_diversity(object, ...)

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

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

Arguments

object: A \(m \times p\) matrix of count data.
...: Further arguments to be passed to internal methods.
adjust: A character string specifying the method for adjusting \(p\) values (see stats::p.adjust()).

Value

A numeric

matrix.

Details

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