These functions return a spectral object of the same class as the one supplied as argument but with the spectral data normalized to 1.o a certain wavelength.

An R object
not used in current version
An R object on which range() returns a numeric vector of
length 2 with the limits of a range of wavelengths in nm, with min and max
wavelengths (nm)
numeric Normalization wavelength (nm) or character string "max", or "min" for normalization at the corresponding wavelength, or "integral" or "mean" for rescaling by dividing by these values.
character Allowed values "energy", and "photon", or its alias "quantum"
character string Allowed values are "transmittance", and "absorbance" indicating on which quantity to apply the normalization.
character vector containing the names of columns or variables to which to apply the normalization.
if TRUE, apply function in parallel, using parallel backend provided by foreach
a list of additional options passed into the foreach function when parallel computation is enabled. This is important if (for example) your code relies on external data or packages: use the .export and .packages arguments to supply them so that all cluster nodes have the correct environment set up for computing.
A copy of x, with spectral data values normalized to one for
the criterion specified by the argument passed to norm.
