Subset SpatRaster by wavelength range

Usage

hsi_subset_range(x, from, to, filename = "", overwrite = FALSE, ...)

Arguments

x: A SpatRaster with hyperspectral data. Band names must be numeric wavelengths in nm.
from: Numeric. Start wavelength of the range in nm, inclusive.
to: Numeric. End wavelength of the range in nm, inclusive.
filename: Character. Output filename. Default "" keeps result in memory.
overwrite: Logical. Overwrite existing file. Default FALSE.
...: Additional arguments passed to terra::writeRaster().

Value
