runifpoint: Generate N Uniform Random Points
Description
Generate a random point pattern
containing $n$ independent uniform random points.Usage
runifpoint(n, win=owin(c(0,1),c(0,1)), giveup=1000)
Arguments
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.
Value
- The simulated point pattern (an object of class
"ppp"
).
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.
Examples
Run this code# 100 random points in the unit square
pp <- runifpoint(100)
