ibr_std

Returns a data frame with standardized values of IBR useful to do a radar chart. This data is fit for our function ibr_chart() from this package that creates this type of plot.

Several functions to calculate two important indexes (IBR (Integrated Biomarker Response) and IBRv2 (Integrated Biological Response version 2)), it also calculates the standardized values for enzyme activity for each index, and it has a graphing function to perform radarplots that make great data visualization for this type of data.
