You can visualize it using analyzeFeatSelResult.


Object members:

learner (Learner)

control (FeatSelControl)

Control object from feature selection.

x (character)

Vector of feature names identified as optimal.

y (numeric)

Performance values for optimal x.

threshold (numeric)

Vector of finally found and used thresholds if tune.threshold was enabled in FeatSelControl, otherwise not present and hence NULL.

opt.path (ParamHelpers::OptPath)

Optimization path which lead to x.
