rMosaicField

From spatstat v1.41-1 by Adrian Baddeley

Mosaic Random Field

Generate a realisation of a random field which is piecewise constant on the tiles of a given tessellation.

Keywords: spatial, datagen

Usage

rMosaicField(X, 
    rgen = function(n) { sample(0:1, n, replace = TRUE)},
    ...,
    rgenargs=NULL)

Arguments

X: A tessellation (object of class "tess").
...: Arguments passed to as.mask determining the pixel resolution.
rgen: Function that generates random values for the tiles of the tessellation.
rgenargs: List containing extra arguments that should be passed to rgen (typically specifying parameters of the distribution of the values).

Details

This function generates a realisation of a random field which is piecewise constant on the tiles of the given tessellation X. The values in each tile are independent and identically distributed.

Value

A pixel image (object of class "im").

Examples

X <- rpoislinetess(3)
   plot(rMosaicField(X, runif))
   plot(rMosaicField(X, runif, dimyx=256))
   plot(rMosaicField(X, rnorm, rgenargs=list(mean=10, sd=2)))

   plot(rMosaicField(dirichlet(runifpoint(30)), rnorm))
