Such a model is created when one sets the corresponding option in <code><a href="/link/configureMlr?package=mlr&version=2.3" rd-options="" data-mini-rdoc="mlr::configureMlr">configureMlr</a></code>.
If no failure occurred, <code>NA</code> is returned.<p></p><p>For complex wrappers this getter returns the first error message encountered in ANY model that failed.</p>

getFailureModelMsg

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.

Data engineering and BI courses are free!

getFailureModelMsg: Return error message of FailureModel.
