Dictionary of FSelectors

A mlr3misc::Dictionary storing objects of class FSelector. Each fselector has an associated help page, see mlr_fselectors_[id].

For a more convenient way to retrieve and construct fselectors, see fs()/fss().

Format

R6::R6Class object inheriting from mlr3misc::Dictionary.

Methods

See mlr3misc::Dictionary.

S3 methods

• as.data.table(dict, ..., objects = FALSE)
  mlr3misc::Dictionary -> data.table::data.table()
  Returns a data.table::data.table() with fields "key", "label", "properties" and "packages" as columns. If objects is set to TRUE, the constructed objects are returned in the list column named object.
