Clamp values to a minimum and maximum value. That is, all values below the lower clamp value and above the upper clamp value become NA (or the lower/upper value if useValue=TRUE)
# S4 method for Raster
clamp(x, lower=-Inf, upper=Inf, useValues=TRUE, filename="", ...)
# S4 method for numeric
clamp(x, lower=-Inf, upper=Inf, ...)Raster object
RasterLayer, or numeric vector
numeric. lowest value
numeric. highest value
logical. If FALSE values outside the clamping range become NA, if TRUE, they get the extreme values
