Hill number summary statistics for `roleData` objects.

These functions calculate Hill numbers. The naming convention indicates what type of Hill number each function calculates; e.g. `hillAbund` calculates abundance-based Hill numbers, while `hillTrait` calculates trait-based Hill numbers.

Usage

hillAbund(x, q = 1:4, ...)

hillGenetic(x, q = 1:4, ...)

hillTrait(x, q = 1:4, ...)

hillPhylo(x, q = 1:4, ...)

richness(x, ...)

Arguments

x

The `roleData` object to calculate Hill numbers or richness from

q

The Hill number exponents. Can be a single value or a vector of integers.

...

additional parameters, ignored
