Webb1 maj 2024 · Description Calculates Chao1 richness of a vector of relative abundance data. This alpha diversity metric takes into account the number of singletons and doubletons for a more accurate estimate than observed richness. Usage Arguments Value Webb1 jan. 2024 · Observed richness, Shannon index and Simpson index were calculated through Hill numbers. Hill numbers are generalizations of alpha diversity that converge to observed richness (order zero), Shannon index (order one) and Simpson index (order two), respectively [12].
Webb12 apr. 2024 · Alpha diversity of microbial communities was assessed using Shannon and Chao1 indices. Bray–Curtis dissimilarity matrices were calculated and used for ordination through principal coordinates analysis . These matrices were also used to determine differences in beta diversity by analysis of similarity (ANOSIM) .
