If x is a collection spectral of objects, such as a
"filter_mspct" object, the returned object is of same class as the
members of the collection, such as "filter_spct", containing the
summary spectrum, with variables with names tagged for summaries other
than mean or median.
An R object. Currently this package defines methods for collections of spectral objects.
logical. A value indicating whether NA values should be stripped before the computation proceeds.

Method specializations compute the range at each wavelength across a
group of spectra stored in an object of one of the classes defined in
package 'photobiology'. Omission of NAs is done
separately at each wavelength. Interpolation is not applied, so all spectra
in x must share the same set of wavelengths. An error is triggered
if this condition is nor fulfilled.
