nlm_randomrectangularcluster

Simulates a random rectangular clusters neutral landscape model with values ranging 0-1.

Usage

nlm_randomrectangularcluster(
  ncol,
  nrow,
  resolution = 1,
  minl,
  maxl,
  rescale = TRUE
)

Arguments

ncol

[numerical(1)]
Number of columns forming the raster.

nrow

[numerical(1)]
Number of rows forming the raster.

resolution

[numerical(1)]
Resolution of the raster.

minl

[numerical(1)]
The minimum possible width and height for each random rectangular cluster.

maxl

[numerical(1)]
The maximum possible width and height for each random rectangular cluster.

rescale

[logical(1)]
If TRUE (default), the values are rescaled between 0-1.

Value

RasterLayer

Details

The random rectangular cluster algorithm starts to fill a raster randomly with rectangles defined by minl and maxl until the surface of the landscape is completely covered. This is one type of realisation of a "falling/dead leaves" algorithm, for more details see Galerne & Gousseau (2012).
