| absorbance_spct {photobiology} | R Documentation |
This function returns the mean absorbance for a given waveband of a absorbance spectrum.
absorbance_spct(spct, w.band, quantity, wb.trim, use.hinges)
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 |
