PM.multispec: Multi-species P-M classfication of Wiegand et al. (2007)

In petrkeil/spasm: Species association measures for various data types

Description

Still under development - use it cautiously

Usage

PM.multispec(X, n.iter, radius)

Arguments

X	Object of class 'ppp' (from 'spatstat' packge). This is a marked point pattern in which each mark gives identity of a species. Thus, the object must have at least 2 species.
n.iter	Number of iterations for simulation from a homogeneous Poisson point process.
r	Radius for which the P and M values should be calculated.

Value

A list.
