A method to compute the sum of values across members of a collections of spectra. Computes the sum at each wavelength across all the spectra in the collection returning a spectral object.
s_sum(x, na.rm, ...)# S3 method for default
s_sum(x, na.rm = FALSE, ...)
# S3 method for filter_mspct
s_sum(x, na.rm = FALSE, ...)
# S3 method for source_mspct
s_sum(x, na.rm = FALSE, ...)
# S3 method for response_mspct
s_sum(x, na.rm = FALSE, ...)
# S3 method for reflector_mspct
s_sum(x, na.rm = FALSE, ...)
# S3 method for calibration_mspct
s_sum(x, na.rm = FALSE, ...)
# S3 method for cps_mspct
s_sum(x, na.rm = FALSE, ...)
# S3 method for raw_mspct
s_sum(x, na.rm = FALSE, ...)
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 sum
of the spectra.
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.
