hci_diff: Calculate difference map

In geohabnet: Geographical Risk Analysis Based on Habitat Connectivity

Calculate difference map

Description

This function produces a map of difference b/w mean and sum indexes in rank of cropland harvested area fraction.

Usage

hci_diff(x, y, global, geoscale, res = reso(), outdir = tempdir())

Arguments

x	SpatRaster.
y	SpatRaster.
global	Logical. TRUE if global analysis is desired, FALSE otherwise. east and west are required when TRUE.
geoscale	Numeric vector. x will be cropped to this extent.
res	Numeric. Map resolution. This value is used in aggregation and dis-aggregation operation. Default is reso().
outdir	Character. Output directory for saving raster in TIFF format. Default is tempdir().

Details

Ideally, the function is tested to yield desired results when length(which(y[] > 0)) > length(which(x[] > 0)).

Value

RiskMap. Contains result in the form of SpatRaster objects and file path of the saved maps.
