IBRv2 (Integrated Biological Responses version 2)

Description

This function calculates de IBRv2 index proposed by Sanchez et al. 2013.

Usage

ibrv2_index(df)

Arguments

df	A data frame containing values the enzymes activities with a reference value on the first rows.

Details

Returns a dataframe with the IBRv2 values for each area/treatment in your input data.

Please cite this package when you use it!

Value

Returns a dataframe with IBRv2 values in comparison to reference treatment

Warnings

You must have at least 3 biomarkers and a maximum of 15 biomarkers to perform this index correctly.

If you have more than one independent variable, it is necessary to separate the data.frame in subsets so there's only one reference value for each level.
