hyperSpec-class: Class "hyperSpec"

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

Description

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.

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

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.

Objects from the Class

Objects can be created by calls of the form new("hyperSpec", spc, data, wavelength, label, log), for details see initialize.

Slots

wavelength:

Numeric vector giving the wavelengths (or wavenumbers, frequencies, m/z, ...) for each data point of the spectrum.

wavelength wavelength axis of the spectra.

data:

data.frame with the spectra and further data for each spectrum (e.g. x/y/z coordinates, times, sample numbers, concentrations, etc.).

The spectra are stored in data$spc, preferrably as a matrix.

label:

List with the labels (character vectors or expressions) that should be used to describe the columns of data.

The label for wavelength is in label$.wavelength.

log:

A data.frame with the columns short.description, long.description, date, and name tracking what is done with the object.
