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