Generate N Uniform Random Points

Generate a random point pattern containing $n$ independent uniform random points.

Keywords
spatial
Usage
runifpoint(n, win=owin(c(0,1),c(0,1)), giveup=1000)
Arguments
n
Number of points.
win
Window in which to simulate the pattern. An object of class "owin" or something acceptable to as.owin.
giveup
Number of attempts in the rejection method after which the algorithm should stop trying to generate new points.
Details

If win is a rectangle then this algorithm simply generates $n$ independent random points uniformly distributed in the rectangle, by assigning uniform random values to their cartesian coordinates.

If win is not a rectangle, the algorithm uses the rejection method. It finds a rectangle enclosing the window, generates points in this rectangle, and tests whether they fall in the desired window. It gives up after giveup consecutive failures have occurred.

Value

  • The simulated point pattern (an object of class "ppp").
