rMosaicSet {spatstat} | R Documentation |
Generate a random set by taking a random selection of tiles of a given tessellation.
rMosaicSet(X, p=0.5)
X |
A tessellation (object of class |
p |
Probability of including a given tile. A number strictly between 0 and 1. |
Given a tessellation X
, this function
randomly selects some of the tiles of X
,
including each tile with probability p independently of
the other tiles. The selected tiles are then combined to form a
set in the plane.
One application of this is Switzer's (1965) example of a random set
which has a Markov property. It is constructed by generating X
according to a Poisson line tessellation (see rpoislinetess
).
A window (object of class "owin"
).
