hill_phylo_parti: Phylogenetic diversity of multiple sites

In hillR: Diversity Through Hill Numbers

Phylogenetic diversity of multiple sites

Description

Calculate overall phylogenetic diversity and site similarity across multiple sites.

Usage

hill_phylo_parti(
  comm,
  tree,
  q = 0,
  base = exp(1),
  rel_then_pool = TRUE,
  show_warning = TRUE,
  check_data = TRUE
)

Arguments

comm	A data frame of vegetation data. Sites as rows, species as columns.
tree	A phylogeny with class 'phylo'.
q	Hill number, q = 0 (default) to get species richness, q = 1 to get shannon entropy, q = 2 will give inverse Simpson.
base	default is exp(1), the base of log.
rel_then_pool	default is TRUE. Abundance of species are first changed to relative abundance within sites, then pooled into one assemblage. If FALSE, sites are pooled first, then change abundance of species to relative abundance.
show_warning	whether to print warning, default is TRUE.
check_data	Whether to check the community data and phylogeny. Default is 'TRUE'. Can be set to 'FALSE' to speed up 'hill_phylo_parti_pairwise()'.

Value

A data frame with one row (across all sites) and six columns: q, gamma diversity, alpha diversity, beta diversity, local similarity (similar to Sorensen), and region similarity (similar to Jaccard).
