%description
Toolset that enriches 'mlr' with a diverse set of preprocessing operators.
Composable Preprocessing Operators ("CPO"s) are first-class R objects that
can be applied to data.frames and 'mlr' "Task"s to modify data, can be
attached to 'mlr' "Learner"s to add preprocessing to machine learning
algorithms, and can be composed to form preprocessing pipelines.
