hurlberts_pie(taxa.wide)
Arguments
taxa.wide
Taxonomic counts aggregated at the specific taxonomic
classification (e.g., Order, Family, or Genus) in a wide data format.
Use the wide function to prepare the data.
Value
Hurlbert's (1971) Probability of Interspecific Encounter (PIE):
PIE = (N/(N-1)) * (1 - sum(p^2))
where:
p = the propotion a specific taxon composes of a sample
N = the total abundance of organisms
This measurement is equivalent to Simpson's Index but includes a correction
factor base on the total abundance of organisms.
