Description: Definitions of classes, methods, operators and functions
        for use in photobiology and radiation meteorology and
        climatology. Calculation of effective (weighted) and
        not-weighted irradiances/doses, fluence rates, transmittance,
        reflectance, absorptance, absorbance and diverse ratios and
        other derived quantities from spectral data. Local maxima and
        minima: peaks, valleys and spikes. Conversion between
        energy-and photon-based units. Wavelength interpolation.
        Colours and vision. This package is part of the
        'r4photobiology' suite, Aphalo, P. J. (2015)
