Return a possibly modified copy of an R object with its class set to a filter
spectrum. In the case of conversion from a solute_spct object, compute
the spectral quantity based on additional input from user.
Usage
as.filter_spct(x, ...)
# Default S3 method
as.filter_spct(
x,
Tfr.type = c("total", "internal"),
strict.range = getOption("photobiology.strict.range", default = FALSE),
...
)
# S3 method for class 'solute_spct'
as.filter_spct(
x,
Tfr.type = "internal",
strict.range = getOption("photobiology.strict.range", default = FALSE),
Rfr.constant = NA_real_,
comment = NULL,
molar.concentration = NULL,
mass.concentration = NULL,
path.length = 1,
...
)Arguments
- x
an R object.
- ...
other arguments passed to "set" functions.
- Tfr.type
a character string, either
"total"or"internal".- strict.range
logical Flag indicating whether off-range values result in an error instead of a warning.
- Rfr.constant
numeric The value of the reflection factor (/1) to be set.
- comment
character A string to be added as a comment attribute to the object created. If not supplied, the comment will be copied from
x.- molar.concentration, mass.concentration
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].
- path.length
numeric The length of the light path (\(m\)) used to compute transmittance of the solute in a solution.
