Dictionary of Task Generators

A simple mlr3misc::Dictionary storing objects of class TaskGenerator. Each task generator has an associated help page, see mlr_task_generators_[id].

This dictionary can get populated with additional task generators by add-on packages.

For a more convenient way to retrieve and construct task generators, see tgen()/tgens().

Format

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