Method returning attributes of an object of class generic_spct or derived,
or of class waveband. Only attributes defined and/or set by package
'photobiology' for objects of the corresponding class are returned. Parameter
which can be used to subset each attribute when a generic_spct object
with multiple spectra in long form is subset.
subset_attributes(x, to.keep, ...)# S3 method for default
subset_attributes(x, to.keep, ...)
# S3 method for generic_spct
subset_attributes(
x,
to.keep = character(),
target.attributes = spct_attributes(class(x)[1]),
...
)
Named list of attribute values.
a generic_spct object.
character vector Indices to the spectra for which attributes are to be extracted and retained.
currently ignored
character vector Names of attributes to be subset using
which.
subset_attributes(default): default
subset_attributes(generic_spct): generic_spct
The values in which are passed as argument to the extract
operator only if the value of the attribute is a list of the same length
as the logical vector passed as argument to which.
