Used as a back-end wrapper for creating new fs methods.
fs.(object, top, uniqueFx, ...)
Specifies the ExprsArray
object to undergo feature selection.
A numeric scalar or character vector. A numeric scalar indicates
the number of top features that should undergo feature selection. A character vector
indicates specifically which features by name should undergo feature selection.
Set top = 0
to include all features. A numeric vector can also be used
to indicate specific features by location, similar to a character vector.
A function call unique to that fs method.
Arguments passed to the respective wrapped function.
Returns an ExprsArray
object.
If the uniqueFx returns a character vector, it is assumed that the fs method is for feature selection only. If the uniqueFx returns a list, it is assumed that the fs method is a reduction model method only.
