absorbance_spct: Calculate absorbance from spectral absorbance.

In photobiology: Photobiological Calculations

Calculate absorbance from spectral absorbance.

Description

This function returns the mean absorbance for a given waveband of a absorbance spectrum.

Usage

absorbance_spct(spct, w.band, quantity, wb.trim, use.hinges, naming, ...)

Arguments

spct	filter_spct
w.band	waveband or list of waveband objects or a numeric vector of length two. The waveband(s) determine the region(s) of the spectrum that are summarized. If a numeric range is supplied a waveband object is constructed on the fly from it.
quantity	character string One of "average" or "mean", "total", "contribution", "contribution.pc", "relative" or "relative.pc"
wb.trim	logical Flag, if TRUE wavebands crossing spectral data boundaries are trimmed and otherwise ignored.
use.hinges	logical Flag indicating whether to use hinges to reduce interpolation errors
naming	character one of "long", "default", "short" or "none". Used to select the type of names to assign to returned value.
...	other arguments (possibly used by derived methods).
