| rmDerivedSpct {photobiology} | R Documentation |
Remove "generic_spct" and derived class attributes.
Description
Removes from a spectrum object the class attributes "generic_spct" and
any derived class attribute such as "source_spct". This
operation is done by reference!
Usage
rmDerivedSpct(x, keep.classes = NULL)
Arguments
x |
an R object. |
keep.classes |
character vector Names of classes to keep. Can be used
to retain base class |
Details
This function alters x itself by reference. If x is
not a generic_spct object, x is not modified. This function
behaves similarly to setdiff() but preserving the original order of
the character vector of the S3 class names.
Value
A character vector containing the removed class attribute values.
This is different to the behaviour of function unlist in base R!
Note
If x is an object of any of the spectral classes defined in this
package, this function changes by reference the spectrum object into the
underlying data.frame object. Otherwise, it just leaves x unchanged.
