Hill {QSutils} | R Documentation

## Hill numbers

### Description

Functions to compute Hill numbers. `Hill` computes the Hill number of a single q value. `HillProfile` computes Hill numbers for all elements in vector `q`.

### Usage

    Hill(w, q)
    HillProfile(w, q = NULL)

### Arguments

`w` | Vector of observed counts or frequencies.
`q` | Exponent.

### Details

In `Hill` , only the first element in q is considered. `HillProfile` is vectorized and considers all elements in `q`.When `q` is NULL: in this case, a default vector is taken to obtain the full profile in the range, 0 to Inf.

### Value

A value or vector of values corresponding to the Hill number estimators of passed exponents.
