# rMosaicSet

##### 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"`

).
