Calculates Shannon's Evenness Index for a given raster object over a specified window size. The function can operate in either sequential or parallel mode.
Usage
Shannon(
x,
window = 3,
rasterOut = TRUE,
np = 1,
na.tolerance = 1,
cluster.type = "SOCK",
debugging = FALSE
)Arguments
- x
A raster object (matrix, SpatRaster, SpatialGridDataFrame, or a list containing one of these).
- window
The size of the moving window to be used for the calculation. Must be an odd integer.
- rasterOut
Logical, if TRUE the output will be a raster object; if FALSE a matrix.
- np
The number of processes to use in parallel mode. If np > 1, parallel computation is enabled.
- na.tolerance
The tolerance level for NA values within the moving window, expressed as a proportion (0 to 1).
- cluster.type
The type of cluster to use for parallel computation (e.g., "SOCK", "FORK").
- debugging
Logical, if TRUE debugging information will be printed.
