Generate a random point pattern, a realisation of the Simple Sequential Inhibition (SSI) process.
rSSI(r, n, win = owin(c(0,1),c(0,1)), giveup = 1000)
r |
Inhibition distance. |
n |
Number of points to generate. |
win |
Window in which to simulate the pattern.
An object of class "owin"
or something acceptable to as.owin.
|
giveup |
Number of rejected proposals after which the algorithm should terminate. |
This algorithm generates a realisation of the Simple Sequential
Inhibition point process
inside the window win.
Starting with an empty window, the algorithm adds points
one-by-one. Each new point is generated uniformly in the window
and independently of preceding points. If the new point lies
closer than r units from an existing point, then it is rejected
and another random point is generated.
The algorithm terminates either when the desired number n
of points is reached, or when the current point configuration
has not changed for giveup iterations.
The simulated point pattern (an object of class "ppp").
