getLearnerModel

Get underlying R model of learner integrated into mlr.

Interface to a large number of classification and regression
techniques, including machine-readable parameter descriptions. There
is also an experimental extension for survival analysis, clustering
and general, example-specific cost-sensitive learning. Generic
resampling, including cross-validation, bootstrapping and subsampling.
Hyperparameter tuning with modern optimization techniques, for single-
and multi-objective problems.  Filter and wrapper methods for feature
selection. Extension of basic learners with additional operations
common in machine learning, also allowing for easy nested resampling.
Most operations can be parallelized.

getLearnerModel function

<dl><dt>model</dt>
<dd>(WrappedModel) 
The model, returned by e.g., train.</dd>
<dt>more.unwrap</dt>
<dd>(<code>logical(1)</code>) 
Some learners are not basic learners from R, but implemented in mlr as meta-techniques.
Examples are everything that inherits from <code>HomogeneousEnsemble</code>.
In these cases, the <code>learner.model</code> is often a list of mlr WrappedModels.
This option allows to strip them further to basic R models.
The option is simply ignored for basic learner models.
Default is <code>FALSE</code>.</dd></dl>
