%description
Machine learning and visualization package with an 'S7' backend featuring
comprehensive type checking and validation, observable runs, and auditable
outputs. The functional API provides one-call access to supervised and
unsupervised learning through train(), cluster(), and decomp(). All
configuration steps are performed using setup functions and validated. A
single call to train() can handle preprocessing, decomposition,
hyperparameter tuning, model stacking, and testing with nested resampling.
Supports 'data.frame', 'data.table', and 'tibble' inputs and parallel
execution. Plot methods for trained and resampled supervised models draw
interactive figures through 'rtemis.draw'. Includes native implementations
of SuperLearner, RuleFit, and Linear Additive Trees, and supports
conformal prediction. The package first appeared in E.D. Gennatas (2017)
