Get or compute the minimum and maximum cell values

The minimum and maximum value of a SpatRaster are returned or computed (from a file on disk if necessary) and stored in the object.

Usage

# S4 method for SpatRaster
minmax(x, compute=FALSE)
# S4 method for SpatRaster
hasMinMax(x)
# S4 method for SpatRaster
setMinMax(x, force=FALSE)

x: SpatRaster
compute: logical. If TRUE min and max values are computed if they are not available
force: logical. If TRUE min and max values are recomputed even if already available

minmax: numeric matrix of minimum and maximum cell values by layer

hasMinMax: logical indicating whether the min and max values are available.

setMinMax: nothing. Used for the side-effect of computing the minimum and maximum values of a SpatRaster

r <- rast(system.file("ex/elev.tif", package="terra"))
minmax(r)
#>     elevation
#> min       141
#> max       547
