(DEPRECATED) Evaluate function on wavelengths of hyperSpec object

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.

_____________

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

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

# S3 method for hyperSpec
wl.eval(x, ..., normalize.wl = I)

# S3 method for numeric
wl.eval(x, ..., normalize.wl = I)

Arguments

x

either hyperSpec object or numeric vector.

...

expressions to be evaluated.

normalize.wl

function to transform the wavelengths before evaluating the polynomial (or other function). Use normalize_01() to map the wavelength range to the interval [0, 1].

Value

hyperSpec object containing one spectrum for each expression.

• vanderMonde() for polynomials,

• normalize_01() to normalize the wavenumbers before evaluating the function.
