Value

This function returns a list with the following components:

Imrp_n

The numerical IMRP index (Rodrigues Capítulo 1999).

Imrp_c

The IMRP index water quality class (Rodrigues Capítulo 1999).

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

Details

IMRP was created for the rivers of the Pampean plain (Rodrigues Capítulo 1999). This index is based on the sum of ecological values for each taxon. This value is inversely proportional to the degree of tolerance to contamination, varying from 0.1 for highly tolerant taxa to 2.0 for the most sensitive. Identification to family is sufficient to calculate the IMRP score.
