Description Usage Arguments Details Value References See Also Examples

Simulates a planar gradient neutral landscape model.

1	nlm_planargradient(ncol, nrow, resolution = 1, direction = NA, rescale = TRUE)

`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.
`direction`	[`numerical(1)`] Direction of the gradient in degrees, if unspecified the direction is randomly determined.
`rescale`	[`logical(1)`] If `TRUE` (default), the values are rescaled between 0-1.

Simulates a linear gradient sloping in a specified or random direction.
