nlm_mosaicfield

Simulates a mosaic random field neutral landscape model.

Usage

nlm_mosaicfield(
  ncol,
  nrow,
  resolution = 1,
  n = 20,
  mosaic_mean = 0.5,
  mosaic_sd = 0.5,
  collect = FALSE,
  infinit = FALSE,
  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.

n

[numerical(1)]
Number of steps over which the mosaic random field algorithm is run

mosaic_mean

[numerical(1)]
Mean value of the mosaic displacement distribution

mosaic_sd

[numerical(1)]
Standard deviation of the mosaic displacement distribution

collect

[logical(1)]
return RasterBrick of all steps 1:n

infinit

[logical(1)]
return raster of the random mosaic field algorithm with infinite steps

rescale

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

Value

RasterLayer or List with RasterLayer/s and/or RasterBrick
