clamp: Clamp values

Description

Clamp values to a minimum and maximum value. That is, all values below a lower threshold value and above the upper threshold value become either NA, or, if values=TRUE, become the threshold value

Usage

# S4 method for SpatRaster
clamp(x, lower=-Inf, upper=Inf, values=TRUE, filename="", ...)
# S4 method for numeric
clamp(x, lower=-Inf, upper=Inf, values=TRUE, ...)

Value

SpatRaster

Arguments

x

SpatRaster

lower

numeric with the lowest acceptable value (you can specify a different value for each layer). Or a SpatRaster that has a single layer or the same number of layers as x

upper

numeric with the highest acceptable value (you can specify a different value for each layer). Or a SpatRaster that has a single layer or the same number of layers as x

values

logical. If FALSE values outside the clamping range become NA, if TRUE, they get the extreme values

filename

character. Output filename

...

additional arguments for writing files as in writeRaster
