icbrio_ind: ICBrio index

Description

Calculate ICBrio index

Usage

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

Value

This function returns a list with the following components:

Icbrio_n

The numerical ICBrio index (Kuhlmann et al. 2012).

Icbrio_c

The ICBrio water quality class (Kuhlmann et al. 2012).

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.

Details

ICBrio was created to monitor the quality of inland waters in the state of São Paulo. It is a multimetric index that includes different metrics: richness, Shannon-Wiener diversity index (H’), Sequential Comparison index (ICS), Tanytarsini/Chironomidae ratio, richness of sensitive taxa and dominance of tolerant groups. Only one of the diversity indices (H’ or ICS) is considered to calculate it (in this case, the function H’ from 'vegan' package). The final value, which generates the diagnosis or classification of habitat quality, combines the arithmetic mean of the value obtained with the sum of the points of each metric.
