Join all spectra in a collection
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.
join_mspct(x, type, ...) ## Default S3 method: join_mspct(x, type = "full", ...) ## S3 method for class 'generic_mspct' join_mspct(x, type = "full", col.name, ...) ## S3 method for class 'source_mspct' join_mspct(x, type = "full", unit.out = "energy", ...) ## S3 method for class 'response_mspct' join_mspct(x, type = "full", unit.out = "energy", ...) ## S3 method for class 'filter_mspct' join_mspct(x, type = "full", qty.out = "transmittance", ...) ## S3 method for class 'reflector_mspct' join_mspct(x, type = "full", ...) ## S3 method for class 'object_mspct' join_mspct(x, type = "full", qty.out, ...)
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". |
An object of class dataframe, with the spectra joined by wave length,
with rows in addition sorted by wave length (variable w.length).

Currently only generic_spct, source_mspct, response_mspct, filter_mspct, reflector_mspct and object_mspct classes have this method implemented.
