HShannon R Documentation
A function to compute Shannon-Wiener diversity (entropy) index
Description
The Shannon-Wiener diversity index is based on
the notion of entropy and measures population heterogeneity.
Usage
HShannon(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
The Shannon-Wiener diversity index value (numeric)
References
Shannon C. E. (1948) A mathematical theory
of communication. Bell System Technical Journal (27)
