Provides the biggest amount of statistical measures in the whole R world. Includes measures of regression, (multiclass) classification and multilabel classification. The measures come mainly from the 'mlr' package and were programed by several 'mlr' developers.

Package that provides the biggest amount of statistical measures in the whole R world!

Includes measures of regression, (multiclass) classification, clustering, survival and multilabel classification.

It is based on measures of mlr.
