DEPRECATED-spc.loess.Rd
These hyperSpec functions are deprecated and not maintained any more. You should not use these. Currently they are present due to back-compatibility reasons and will be removed in the next release of the package. Please, use the suggested alternative functions instead.

Spectra smoothing and interpolation on a new wavelength axis using
stats::loess()
.
spc.loess(spc, newx, enp.target = nwl(spc)/4, surface = "direct", ...)
spc | The |
---|---|
newx | Wavelength axis to interpolate on. |
enp.target, surface, ... | Further parameters for |
A new hyperSpec
object.
Applying stats::loess()
to each of the spectra, an interpolation onto a new
wavelength axis is performed. At the same time, the spectra are smoothed in
order to increase the signal to noise ratio. See stats::loess()
and
stats::loess.control()
on the parameters that control the amount of
smoothing.
