metrix (version 1.1.0)

biotic_ind: Biotic indexes

Description

Calculates BMWP, BMWP', BMWP'', IMRP and ICBrio indexes

Usage

biotic_ind(dataset, store = FALSE, dec_c = ".", verbose = FALSE)

Value

This function returns a list with the following components:

bioind_n

The numerical values of the biotic indexes.

bioind_c

The water quality class assign to each sample site according to the numerical value of the biotic indexes

Arguments

dataset

A data.frame obtained from read_data.

store

A logical value indicating if the user want to store the results in a file.

dec_c

A character used for decimal separator on results file.

verbose

A logical value indicating if progress messages should be given.

Author

Juan Manuel Cabrera and Julieta Capeletti.

Details

The biotic indicators consist of the combination of two or three properties of the association: taxa richness and tolerance/intolerance to contamination for qualitative indices, and these together with abundance (absolute or relative) for quantitative indices. They are usually expressed in the form of a single numerical value that synthesizes the characteristics of all the species present.
