Generate a random point pattern, a simulated realisation of the Mat'ern Model I inhibition process model.
rMaternI(kappa, r, win = owin(c(0,1),c(0,1)))
kappa |
Intensity of the Poisson process of proposal points. A single positive number. |
r |
Inhibition distance. |
win |
Window in which to simulate the pattern.
An object of class "owin"
or something acceptable to as.owin.

This algorithm generates a realisation of Mat'ern's Model I
inhibition process
inside the window win.
The process is constructed by first
generating a uniform Poisson point process of ``proposal'' points
with intensity kappa inside the window.
A proposal point is deleted if it lies within r units' distance
of another proposal point. Otherwise it is retained.
The retained points constitute Mat'ern's Model I.
The simulated point pattern (an object of class "ppp").
