Query if an object has old class names Query if an object has old class names
as used in photobiology (&gt;= 0.6.0).

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. Astronomical calculations related solar angles and
day length. Colours and vision. This package is part of the 'r4photobiology'
