join_mspct: Join all spectra in a collection

Description

Join all the spectra contained in a homogenous collection, returning a data frame with spectral-data columns named according to the names of the spectra in the collection. By default a full join is done, filling the spectral data for missing wave lengths in individual spectra with NA.

Usage

join_mspct(x, type, ...)

# S3 method for default join_mspct(x, type = "full", ...)

# S3 method for generic_mspct join_mspct(x, type = "full", col.name, ...)

# S3 method for source_mspct join_mspct(x, type = "full", unit.out = "energy", ...)

# S3 method for response_mspct join_mspct(x, type = "full", unit.out = "energy", ...)

# S3 method for filter_mspct join_mspct(x, type = "full", qty.out = "transmittance", ...)

# S3 method for reflector_mspct join_mspct(x, type = "full", ...)

# S3 method for object_mspct join_mspct(x, type = "full", qty.out, ...)

Arguments

x

A generic_mspct object, or an object of a class derived from generic_mspct.

type

character Type of join: "left", "right", "inner" or "full" (default). See details for more information.

...

ignored (possibly used by derived methods).

col.name

character, name of the column in the spectra to be preserved, in addition to "w.length".

unit.out

character Allowed values "energy", and "photon", or its alias "quantum".

qty.out

character Allowed values "transmittance", and "absorbance".

Value

An object of class dataframe, with the spectra joined by wave length, with rows in addition sorted by wave length (variable w.length).
