acos.generic_spct

asin.generic_spct

atan.generic_spct

Trigonometric functions for object of <code>generic_spct</code> and derived
classes. \
The functions are applied to the spectral data, not the wavelengths. The
quantity in the spectrum to which the function is applied depends on the class
of <code>x</code> and the current value of output options.

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'
suite, Aphalo, P. J. (2015) <doi:10.19232/uv4pb.2015.1.14>.
