%description
Machine learning and visualization package with an 'S7' backend featuring
comprehensive type checking and validation, paired with an efficient
functional user-facing API. train(), cluster(), and decomp() provide
one-call access to supervised and unsupervised learning. All configuration
steps are performed using setup functions and validated. A single call to
train() handles preprocessing, hyperparameter tuning, and testing with
nested resampling. Supports 'data.frame', 'data.table', and 'tibble'
inputs, parallel execution, and interactive visualizations. The package
first appeared in E.D. Gennatas (2017)
