clamp function

Clamp values

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

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

## S4 method for signature 'numeric'
clamp(x, lower=-Inf, upper=Inf, values=TRUE, ...)

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

Returns

SpatRaster
