raster.Zscore

From spatialEco v1.3-2 by Jeffrey S Evans

Modified z-score for a raster

Calculates the modified z-score for all cells in a raster

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

# NOT RUN {
library(raster)
r <- raster(nrows=824, ncols=767, xmn=2451905, xmx=3218905, 
            ymn=-2744771, ymx=-1920771, resolution = 5000)
  r[] <- runif(ncell(r), 0, 1)

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

# P-value
p <- raster.Zscore(r, p.value = TRUE)
# }
# NOT RUN {
# }
