WebHill numbers computation Description. Compute neutral or phylogenetic Hill numbers from a single sample (vector) or count table (matrix). Hill numbers or numbers equivalents of diversity indices are diversity measures that compute diversity in effective number of OTUs, i.e. the number of equally abundant OTUs that would be needed to give the same value of … WebhillR hillR: Diversity Through Hill Numbers Description The R package ‘hillR‘ implements the framework proposed by Chao, et al. 2014 and makes it easy to calculate taxonomic, functional, and phylogenetic diversity of ecological communities as Hill numbers. For each facet of diversity, ‘hillR‘ has three functions. The first set of functions
When diversity indices are used in ecology, the types of interest are usually species, but they can also be other categories, such as genera, families, functional types, or haplotypes. The entities of interest are usually individual plants or animals, and the measure of abundance can be, for example, number of individuals, biomass or coverage. In demography, the entities of interest can be people, and the types of interest various demographic groups. In information science, the enti…
