hyperSpec {hyperSpec} | R Documentation |
This package gives an interface to handle hyperspectral data sets in R. Hyperspectral data are spatially or time-resolved spectra, or spectra with any other kind of information associated with the spectra. E.g. spectral maps or images, time series, calibration series, etc.
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.
The following vignettes should provide a start:

chondro | Vignette on the chondro data set (Raman map). Shows common Preprocessing tasks for Raman spectra, principal component analysis (PCA), and hierarchical cluster analysis. (source, pdf) |
flu | flu: Vignette on a small fluorescence data set, how to write an import function, and example of a linear calibration (source, pdf) |
