Description Usage Arguments Value Author(s) Examples
This function takes a raster stack or raster object and creates two matrices for each raster layer, one which contains the x coordinates of the gradient of the raster layer and one which contains the y coordinates of the gradient of the raster layer.

|
rasterstack |
A raster layer or raster stack from package "raster". |
xy |
A matrix of x and y coordinates of each cell in the raster stack or raster layer. The order is the order of the cells in the raster object. |
grad.x |
a matrix where each column is the x-coordinates of the gradient for one raster layer |
grad.y |
a matrix where each column is the y-coordinates of the gradient for one raster layer |
rast.grad.x |
A raster stack where each raster layer is the x-coordinates of the gradient for one covariate |
rast.grad.y |
A raster stack where each raster layer is the x-coordinates of the gradient for one covariate |
