R: Calculate absorbance from spectral absorbance.

absorbance_spct {photobiology} | R Documentation

## 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)

### 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 wavebands crossing spectral data boundaries are trimmed or ignored
`use.hinges` | logical Flag indicating whether to use hinges to reduce interpolation errors
