calculate_spatial_autocorrelation — calculate_spatial_autocorrelation • SPIAT

Takes the result of grid_metrics (a RasterLayer object) and calculate its spatial autocorrelation.

Usage

calculate_spatial_autocorrelation(raster_obj, metric = "globalmoran")

Arguments

raster_obj: Raster object in the form of the output of grid_metrics.
metric: String. The method for calculating spatial autocorrelation. Choose from "globalmoran" and "GearyC".

Value

A number is returned

Examples

grid <- grid_metrics(SPIAT::defined_image, FUN = calculate_entropy, n_split = 5,
cell_types_of_interest=c("Tumour","Immune3"), feature_colname = "Cell.Type")

calculate_spatial_autocorrelation(grid, metric = "globalmoran")
