BMWP prime prime index

Description

Calculate Biological Monitoring Working Party (BMWP) prime prime index (Loyola, 2000)

Usage

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

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.

Details

The new BMWP’’ is an adaptation of the BMWP (Armitage et al. 1983) for the lotic environments of the Paraná River. This adaptation was based on the observation of the occurrence of the important families in the rivers in the region. Some families were added by ecological equivalence and others by similarity in the level of tolerance to contamination. The scores assigned to the different families were not changed (Loyola, 2000).

Value

This function returns a list with the following components:

Ibmwp_p_p_n	The numerical BMWP’’ index (Loyola, 2000).
Ibmwp_p_p_c	The BMWP’’ water quality classes (Loyola, 2000).
