Use 'Phosphor' icons in 'shiny' applications or 'rmarkdown' documents. Icons are available in
    5 different weights and can be customized by setting color, size, orientation and more.

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) <doi:10.19232/uv4pb.2015.1.14>.

Spectral 'transmittance' data for frequently used filters and 
    similar materials. Plastic sheets and films; photography filters; 
    theatrical gels; machine-vision filters; various types of window glass;
    optical glass and some laboratory plastics and glassware. Spectral 
    reflectance data for frequently encountered materials. Part of the
    'r4photobiology' suite, Aphalo P. J. (2015) <doi:10.19232/uv4pb.2015.1.14>.

Functions for reading, and in some cases writing, foreign files 
    containing spectral data from spectrometers and their associated software, 
    output from daylight simulation models in common use, and some spectral 
    data repositories. As well as functions for exchange of spectral data with 
    other R packages. Part of the 'r4photobiology' suite, 
    Aphalo P. J. (2015) <doi:10.19232/uv4pb.2015.1.14>.

Spectral emission data for some frequently used lamps including 
    bulbs and flashlights based on led emitting diodes (LEDs) but excluding
    LEDs available as electronic components. Original spectral irradiance data 
    for incandescent-, LED- and discharge lamps are included. They are 
    complemented by data on the effect of temperature on the emission by 
    fluorescent tubes. Part of the 'r4photobiology' suite, Aphalo P. J. (2015) 
    <doi:10.19232/uv4pb.2015.1.14>.
