hyperSpec-class {hyperSpec}

Class "hyperSpec" This class handles hyperspectral data sets, i.e. spatially or time-resolved spectra, or spectra with any other kind of information associated with the spectra.

Description

The spectra can be data as obtained in XRF, UV/VIS, Fluorescence, AES, NIR, IR, Raman, NMR, MS, etc.

Details

More generally, any data that is recorded over a discretized variable, e.g. absorbance = f (wavelength), stored as a vector of absorbance values for discrete wavelengths is suitable.

Slots

wavelength

wavelengths (wavenumbers, frequencies, etc.) for each of the columns of the spectra matrix

data

the data (extra data and spectra matrix)

label

expressions for column labels (incl. units). The label of the wavelength axis is in the special element .wavelength.

log

deprecated.

Note

Please note that the logbook is now removed.
