s_mean_se_band: Mean plus and minus standard error from collection of spectra

Description

Method to compute the "parallel" mean and limits based on SEM. The spectral values are summarised across members of a collection of spectra or of a spectral object containing multiple spectra in long form.

Usage

s_mean_se_band(x, na.rm, mult, ...)

# S3 method for default s_mean_se_band(x, na.rm = FALSE, mult = 1, ...)

# S3 method for generic_spct s_mean_se_band(x, na.rm = FALSE, mult = 1, ...)

# S3 method for filter_mspct s_mean_se_band(x, na.rm = FALSE, mult = 1, ...)

# S3 method for source_mspct s_mean_se_band(x, na.rm = FALSE, mult = 1, ...)

# S3 method for response_mspct s_mean_se_band(x, na.rm = FALSE, mult = 1, ...)

# S3 method for reflector_mspct s_mean_se_band(x, na.rm = FALSE, mult = 1, ...)

# S3 method for calibration_mspct s_mean_se_band(x, na.rm = FALSE, mult = 1, ...)

# S3 method for cps_mspct s_mean_se_band(x, na.rm = FALSE, mult = 1, ...)

# S3 method for raw_mspct s_mean_se_band(x, na.rm = FALSE, mult = 1, ...)

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.

na.rm

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

mult

numeric number of multiples of standard error.

...

Further arguments passed to or from other methods.

Details

Method specializations compute the mean and limits based on SEM 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. The value passed as argument to `mult` can be used to estimate a confidence interval for each mean value.
