In NLMR: Simulating Neutral Landscape Models

Description Usage Arguments Details Value See Also Examples

Simulates a distance-gradient neutral landscape model.

1	nlm_distancegradient(ncol, nrow, resolution = 1, origin, 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.
`origin`	[`numerical(4)`] Edge coordinates of the origin (raster::extent with xmin, xmax, ymin, ymax) of the distance measurement.
`rescale`	[`logical(1)`] If `TRUE` (default), the values are rescaled between 0-1. Otherwise, the distance in raster units is calculated.

The function takes the number of columns and rows as input and creates a RasterLayer with the same extent. Origin is a numeric vector of xmin, xmax, ymin, ymax for a rectangle inside the raster from which the distance is measured.
