# S4 method for Raster
scale(x, center=TRUE, scale=TRUE)
Value
Raster* object
Arguments
x
Raster* object
center
logical or numeric. If TRUE, centering is done by subtracting the layer means (omitting NAs), and if FALSE, no centering is done. If center is a numeric vector with length equal to the nlayers(x), then each layer of x has the corresponding value from center subtracted from it.
scale
logical or numeric. If TRUE, scaling is done by dividing the (centered) layers of x by their standard deviations if center is TRUE, and the root mean square otherwise. If scale is FALSE, no scaling is done. If scale is a numeric vector with length equal to nlayers(x), each layer of x is divided by the corresponding value. Scaling is done after centering.
