clip_wl.waveband

a numeric vector of length two, or any other object for which
function <code>range()</code> will return range of walengths expressed in
nanometres.

range


Clipping of head and tail of a spectrum based on wavelength limits, no
interpolation used.


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.
