In INDperform: Evaluation of Indicator Performances for Assessing Ecosystem States

INDperform

INDperform is an R package for validating the performance of ecological state indicators and assessing the ecological status based on a suite of indicators.

Install the CRAN version:

install.packages("INDperform")

Or install the development version from GitHub:

# install.packages("devtools")
devtools::install_github("saskiaotto/INDperform")

If you encounter a clear bug, please file a minimal reproducible example on github. For questions email me any time.

For more information, documentation and examples of use, please see INDperform website at https://saskiaotto.github.io/INDperform/

For guidance on how to apply the functions step-by-step see also the INDperform cheatsheet. We are currently working on the Vignette but if you want more information on the framework for quantifying IND performances and its statistical tools implemented in this package see

In Version 0.2.1, a minor bug with different internal test results under different R versions was fixed by modifying some tests. But this bug did not affect the modelling results or performance of the previous version.

Version 0.2.0 has been released on CRAN 2019-02-10! The new version includes a few internal changes as adjustments to updated packages it depends on. Major changes changes include a new NRMSE calculation based on the standard deviation and back-transformation (see https://www.marinedatascience.co/blog/2019/01/07/normalizing-the-rmse/ for the motivation), an NRMSE stand-alone function (nrmse()) and a function that allows the calculation of the distance matrix averaged across groups (i.e. a weighted distance matrix) (dist_sc_group()).
