Mosaic Random Set
Generate a random set by taking a random selection of tiles of a given tessellation.
Usage
rMosaicSet(X, p=0.5)
Arguments
- X
- A tessellation (object of class
"tess"
). - p
- Probability of including a given tile. A number strictly between 0 and 1.
Details
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
).
Value
- A window (object of class
"owin"
).
