wl.eval: Evaluate function on wavelengths of hyperSpec object

In hyperSpec: Work with Hyperspectral Data, i.e. Spectra + Meta Information (Spatial, Time, Concentration, ...)

Evaluate function on wavelengths of hyperSpec object

Description

This is useful for generating certain types of baseline "reference spectra".

Usage

wl.eval(x, ..., normalize.wl = I)

Arguments

x	hyperSpec object
...	hyperSpec method: expressions to be evaluated
normalize.wl	function to transorm the wavelengths before evaluating the polynomial (or other function). Use normalize01 to map the wavelength range to the interval [0, 1].

Value

hyperSpec object containing one spectrum for each expression
