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

A numeric matrix containing the local diversity index values for each spatial unit
