<p>Functions to check if an object is of a given type of spectrum, or coerce it if
possible.</p>

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. Conversion between energy- and photon-based units. Wavelength
interpolation. Astronomical calculations related solar angles and day
length. Colours and vision. This package is part of the
'r4photobiology' suite, Aphalo P. J. (2015) <doi:10.19232/uv4pb.2015.1.14>.
