Calculate variance of CCRI — hci_variance • geohabnet

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()
)

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().

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