brillouin: Brillouin's index
In EDiLD/qetx: Quantitative Ecotoxicology with R

Calculate Brillouin's diversity index

1	brillouin(x, base = exp(1))

`x`	Community data
`base`	The logarithm `base` used.

Brillouin's index is defined as H = \frac{1}{N} Ln (\frac{N!}{∏_{n=1}^S n_i!})

where N = Total number of idividuals in the sample and n_i number of species i in the sample.

A vector of brillouins index.
