Subset SpatRaster by wavelength

Usage

hsi_subset(x, wavelength, filename = "", overwrite = FALSE, ...)

Arguments

x: A SpatRaster with hyperspectral data. Band names must be numeric wavelengths in nm.
wavelength: Numeric vector. Wavelength(s) to extract in nm. Nearest available band is selected for each value.
filename: Character. Output filename. Default "" keeps result in memory.
overwrite: Logical. Overwrite existing file. Default FALSE.
...: Additional arguments passed to terra::writeRaster().

Value

A SpatRaster subset to the requested wavelength(s).
