Calculate variance of habitat connectivity in a region

This function produces a map of variance of habitat connectivity across selected parameter values

Usage

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

indices: SpatRaster. Collection of risk indices.
rast: SpatRaster. Template for variance output
global: Logical. Select TRUE if a 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. This refers to the geographical extent for the habitat connectivity analysis when global is set to FALSE. Default is NULL.
res: Numeric. This parameter refers to the spatial aggregation factor. This value is the number of cells that are grouped when aggregating a raster layer from fine to coarse spatial resolution to reduce computational costs. Setting this parameter to 1 would not aggregate the raster layers. Default is reso().
outdir: Character. Output directory for saving raster in TIFF format. Default is tempdir().

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