s_se: Standard Error of a collection of spectra

Description

Method to compute the "parallel" standard error of the mean across members of a collection of spectra or of a spectral object containing multiple spectra in long form.

Usage

s_se(x, na.rm, ...)

# S3 method for default s_se(x, na.rm = FALSE, ...)

# S3 method for generic_spct s_se(x, na.rm = FALSE, ...)

# S3 method for source_mspct s_se(x, na.rm = FALSE, ...)

# S3 method for response_mspct s_se(x, na.rm = FALSE, ...)

# S3 method for filter_mspct s_se(x, na.rm = FALSE, ...)

# S3 method for reflector_mspct s_se(x, na.rm = FALSE, ...)

# S3 method for calibration_mspct s_se(x, na.rm = FALSE, ...)

# S3 method for cps_mspct s_se(x, na.rm = FALSE, ...)

# S3 method for raw_mspct s_se(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 summary spectrum, with variables with names tagged for summaries other than mean or median.

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.

Methods (by class)

  • s_se(default):

  • s_se(generic_spct):

  • s_se(source_mspct):

  • s_se(response_mspct):

  • s_se(filter_mspct):

  • s_se(reflector_mspct):

  • s_se(calibration_mspct):

  • s_se(cps_mspct):

  • s_se(raw_mspct):

Details

Method specializations compute the standard error of the mean 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.
