bmwp_p_ind: BMWP prime index

In metrix: Water Quality Metrics Calculator

BMWP prime index

Description

Calculate Biological Monitoring Working Party (BMWP) prime index.

Usage

bmwp_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 BMWP’ is an adaptation of the BMWP (Armitage et al. 1983) created to evaluate the biological quality of the Iberian Peninsula. Most of the macroinvertebrate families living in the Iberian Peninsula have been added to the original index and some of the scores have been changed (Alba Tercedor & Sánchez Ortega 1988).

Value

This function returns a list with the following components:

Ibmwp_p_n	The numerical BMWP’ index (Alba Tercedor and Sánchez Ortega 1988).
Ibmwp_p_c	The BMWP’ index water quality classes (Alba Tercedor and Sánchez Ortega 1988).
