benchmark.
The structure of the object itself is rather complicated, it is recommended to
retrive required information via link{getAggrPerformances}, link{getPredictions},
getPerformances, getFeatSelResult, getTuneResult or
getFilterResult. Alternatively, you can convert the object using
as.data.frameFilterResult,
getFilterResult; benchmark;
getAggrPerformances;
getFeatSelResult;
getPerformances;
getPredictions; getTuneResult
