%description
Provides a unified tidyverse-compatible interface to R's machine learning
ecosystem - from data ingestion to model publishing. The tl_read() family
reads data from files ('CSV', 'Excel', 'Parquet', 'JSON'), databases
('SQLite', 'PostgreSQL', 'MySQL', 'BigQuery'), and cloud sources ('S3',
'GitHub', 'Kaggle'). The tl_model() function wraps established
implementations from 'glmnet', 'randomForest', 'xgboost', 'e1071',
'rpart', 'gbm', 'nnet', 'cluster', 'dbscan', and others with consistent
function signatures and tidy tibble output. Results flow into unified
'ggplot2'-based visualization and optional formatted 'gt' tables via the
tl_table() family. The underlying algorithms are unchanged; 'tidylearn'
simply makes them easier to use together. Access raw model objects via the
$fit slot for package-specific functionality. Methods include random
