hci_variance: Calculate variance of CCRI

In geohabnet: Geographical Risk Analysis Based on Habitat Connectivity

Calculate variance of CCRI

Description

This function produces a map of variance of CCRI based on input parameters

Usage

hci_variance(
  indices,
  rast,
  global,
  east = NULL,
  west = NULL,
  geoscale,
  res = reso(),
  outdir = tempdir()
)

Arguments

indices	SpatRaster. Collection of risk indices.
rast	SpatRaster. Template for variance output
global	Logical. TRUE if global analysis is desired, FALSE otherwise. east and west are required when TRUE.
east	SpatRaster. Collection of risk indices on eastern extent.
west	SpatRaster. Collection of risk indices on western extent. When TRUE, geoscale is ignored. Default is TRUE.
geoscale	Vector. geographical scale. Default is NULL.
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().

Value

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