convert_task

The task's target is replaced by a different column from the data.

Efficient, object-oriented programming on the
building blocks of machine learning. Provides 'R6' objects for tasks,
learners, resamplings, and measures. The package is geared towards
scalability and larger datasets by supporting parallelization and
out-of-memory data-backends like databases. While 'mlr3' focuses on
the core computational operations, add-on packages provide additional
functionality.

convert_task function

<dl><dt>intask</dt>
<dd>(Task) 
A Task to be converted.</dd>
<dt>target</dt>
<dd>(<code>character(1)</code>) 
New target to be set, must be a column in the <code>intask</code> data.
If <code>NULL</code>, no new target is set, and task is converted as-is.</dd>
<dt>new_type</dt>
<dd>(<code>character(1)</code>) 
The new task type. Must be in <code>mlr_reflections$task_types</code>].
If <code>NULL</code> (default), a new task with the same task_type is created.</dd>
<dt>drop_original_target</dt>
<dd>(<code>logical(1)</code>) 
If <code>FALSE</code> (default), the original target is added as a feature.
Otherwise the original target is dropped.</dd>
<dt>drop_levels</dt>
<dd>(<code>logical(1)</code>) 
If <code>TRUE</code> (default), unused levels of the new target variable are dropped.</dd></dl>
