Description

The Shannon-Wiener diversity index is based on the notion of entropy and measures population heterogeneity.

Usage

1

Arguments

x

- an object of class matrix (or which can be coerced to that class), where each column represents the distribution of a group within spatial units. The number of columns should be greater than 1 (at least 2 groups are required). You should not include a column with total population, because this will be interpreted as a group.

Value

Shannon-Wiener diversity index
