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.
stationary
Logical. Whether to start with a stationary process of proposal points
(stationary=TRUE) or to generate the
proposal points only inside the window (stationary=FALSE).
Value
The simulated point pattern (an object of class "ppp").
Details
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. If stationary = TRUE (the
default), the proposal points are generated in a window larger than
win that effectively means the proposals are stationary.
If stationary=FALSE then the proposal points are
only generated inside the window win.
A proposal point is then 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.
