sim.comm.jittered: Function that simulates a "jittered" community

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

Description

The simulation proceeds as: 1. Generate point pattern for the most abundant (master) species, with a given variance 'var.consp' giving the spread of the points along the x and y axis 2. Generate smoothed density of the master points, with a given gaussian kernel width 'var.intersp'. The steeper the kernel, the closer will be the points of the other species to the mother species. 3. For each other species in the vector, draw points from the smoothed density surface, with a given abundance Note: Master species is the most abundant species, i.e. species 1.

Usage

sim.comm.jittered(abund.vect, var.consp, var.intersp)

Arguments

abund.vect	vector of (integer) abundances of species in a community
var.consp	conspecific variance, i.e. spread of points in the master species
var.intersp	interspecific variance, i.e. width of the density kernel
