raster.Zscore: Modified z-score for a raster

In spatialEco: Spatial Analysis and Modelling Utilities

Modified z-score for a raster

Description

Calculates the modified z-score for raster values

Usage

raster.Zscore(x, p.value = FALSE, file.name = NULL, ...)

Arguments

x	A raster class object
p.value	Return p-value rather than z-score raster (FALSE/TRUE)
file.name	Name of raster written to disk
...	Additional arguments passed to writeRaster

Value

raster class object or raster written to disk

Note

Since this functions needs to operate on all of the raster values, it is not memory safe

Examples

library(terra)
r <- rast(nrows=500, ncols=500)
  r[] <- runif(ncell(r), 0, 1)

# Modified z-score
( z <- raster.Zscore(r) )

# P-value
( p <- raster.Zscore(r, p.value = TRUE) )
