DiaThor: R package for computing diatom metrics and biotic indices

Abstract

Diatom-based tools like biotic indices, ecological and morphological traits, are widely used to detect changes in water quality. Here we present DiaThor, a free and open source R package for calculating biotic and ecological indices and metrics for diatom samples. A web application (in Shiny) was also developed to provide access to the package for those users not familiar with the R environment.
