absorptance_spct: Calculate absorptance from spectral absorptance.

Description

This function returns the summary absorptance for a given waveband of a object_spct object

Usage

absorptance_spct(
  spct,
  w.band = NULL,
  quantity = "average",
  wb.trim = getOption("photobiology.waveband.trim", default = TRUE),
  use.hinges = getOption("photobiology.use.hinges", default = NULL)
)

Arguments

spct

object_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", "contribution", "contribution.pc", "relative" or "relative.pc"

wb.trim

logical if TRUE wavebands crossing spectral data boundaries are trimmed, if FALSE, they are discarded

use.hinges

logical indicating whether to use hinges to reduce interpolation errors
