Return a possibly modified copy of an R object with its class set to
solute_spct
(a solute spectrum). In the case of conversion from a
filter_spct
object, compute spectral molar attenuation based on
additional input from user.

A copy of x
converted into a solute_spct
object.
an R object.
other arguments passed to "set" functions.
a character string, one of "attenuation"
,
"absorption"
or "scattering"
.
logical Flag indicating whether off-range values result in an error instead of a warning.
character The names of the substance and of the solvent. A named character vector, with member names such as "IUPAC" for the authority.
numeric The mass in Dalton (Da = g/mol).
character The molecular formula.
raster A bitmap of the structure.
character The IDs of the substance and of the solvent. A named character vector, with member names such as "ChemSpider" or "PubChen" for the authority.
character A string to be added as a comment attribute to the
object created. If not supplied, the comment will be copied from x
.
numeric Concentration to be used to compute transmittance of the solute in solution [\(mol\,m^{-3} = mmol\,dm^{-3}\) or \(kg\,m^{-3} = g\,dm^{-3}\), respectively].
numeric The length of the light path (\(m\)) used to compute transmittance of the solute in a solution.
