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 {
# }
