%description
A unified interface is provided to various machine learning algorithms
like linear or quadratic discriminant analysis, k-nearest neighbors,
random forest, support vector machine, ... It allows to train, test, and
apply cross-validation using similar functions and function arguments with
a minimalist and clean, formula-based interface. Missing data are
processed the same way as base and stats R functions for all algorithms,
both in training and testing. Confusion matrices are also provided with a
rich set of metrics calculated and a few specific plots.
