'A collection of measures for measuring ecological diversity. Ecological diversity comes in two flavors: alpha diversity measures the diversity within a single site or sample, and beta diversity measures the diversity across two sites or samples. This package overlaps considerably with other R packages such as ''vegan'', ''gUniFrac'', ''betapart'', and ''fossil''. We also include a wide range of functions that are implemented in software outside the R ecosystem, such as ''scipy'', ''Mothur'', and ''scikit-bio''. The implementations here are designed to be basic and clear to the reader.'
