Point Process Methods 137
To develop some intuition about c ompletely random patterns, it is useful to repeat the command
plot(rpoispp(100)) several times (use the up-arrow key or Ctrl-P to recall the previous com-
mand line ) so that you see several replicate s of the Poisson process. Alternatively
> plot(rpoispp(100, nsim=9))
would produce a 3×3 array of different realisations of the same constant intensity Poisson process.
In particular you will notice that the points in a homogeneous Poisson process are not ‘uniformly
spread’: there are emp ty gaps and clusters of points. A typical realisation of the process does not
show a uniform spread of points: ...
