s_median: Median of a collection of spectra

Description

A method to compute the median of values across members of a collections of spectra. Computes the median at each wavelength across all the spectra in the collection returning a spectral object.

Usage

s_median(x, na.rm, ...)
# S3 method for default
s_median(x, na.rm = FALSE, ...)
# S3 method for source_mspct
s_median(x, na.rm = FALSE, ...)
# S3 method for response_mspct
s_median(x, na.rm = FALSE, ...)
# S3 method for filter_mspct
s_median(x, na.rm = FALSE, ...)
# S3 method for reflector_mspct
s_median(x, na.rm = FALSE, ...)
# S3 method for calibration_mspct
s_median(x, na.rm = FALSE, ...)
# S3 method for cps_mspct
s_median(x, na.rm = FALSE, ...)
# S3 method for raw_mspct
s_median(x, na.rm = FALSE, ...)

Value

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 median spectrum.

Arguments

x

An R object. Currently this package defines methods for collections of spectral objects.

na.rm

logical. A value indicating whether NA values should be stripped before the computation proceeds.

Further arguments passed to or from other methods.
