getFeatureImportanceLearner

This function is mostly for internal usage. To calculate feature importance use getFeatureImportance.
The return value is a named numeric vector. There does not need to be one value for each feature in the dataset.
In getFeatureImportance missing features will get an importance of zero and if the vector contains <code>NA</code>
they will also be replaced with zero.

internal

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.
