Description

Local diversity index, HLoc, is a local adaptation of Pielou's normalized diversity index NShannon.

Usage

1
HLoc(x)

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

a numeric vector containing diversity index value for each group
