In mlr-org/mlr3ordinal: Ordinal regression for mlr3

Convert a task from its type to another.

Description

THIS IS A COPY FROM MLR3PIPELINES!

Usage

convert_task(
  intask,
  new_target = NULL,
  new_type = NULL,
  drop_original_target = TRUE,
  drop_levels = FALSE,
  ...
)

Arguments

intask	Task A Task to be converted.
new_target	character(1) | NULL New target to be set, must be a column in the intask data. If NULL, no new target is set, and task is converted as-is.
new_type	character(1) | NULL The new task type. Must be in mlr_reflections$task_types. If NULL (default), a new task with the same task_type is created.
drop_original_target	logical(1) If TRUE (default), the original target is dropped. Otherwise it is added as a feature.
drop_levels	logical(1) If TRUE, unused levels of the new target variable are dropped.
...	any Further arguments passed to the constructor of the task.

Details

The task's target is replaced by a different column from the data. #FIXME: This needs detailed tests and should be moved to mlr3.
