shannon

shannon_

Compute entropy according to Shannon (1948)

Preprocessing tools and biodiversity measures
(species abundance, species richness, population heterogeneity and
sensitivity) for analysing marine benthic data. See Van Loon et al.
(2015) <doi:10.1016/j.seares.2015.05.002> for an application of
these tools.
