%description
Fast and extensible framework for discovering interesting patterns in
tabular data. The package searches combinations of fuzzy or Boolean
predicates and evaluates the resulting subgroups using statistical,
logical, or structural measures. It supports a broad range of
pattern-discovery tasks, including association rules (Agrawal et al.,
1994, <https://www.vldb.org/conf/1994/P487.PDF>), contrast patterns (Chen,
2022, <doi:10.48550/arXiv.2209.13556>), emerging patterns (Dong et al.,
1999, <doi:10.1145/312129.312191>), subgroup discovery (Atzmueller, 2015,
<doi:10.1002/widm.1144>), and conditional correlations (Hájek, 1978,
<doi:10.1007/978-3-642-66943-9>). User-defined functions may be supplied
to guide custom pattern searches, making the framework applicable beyond
traditional association-rule mining. Efficient implementation enables
pattern discovery on large and dense data sets. Package includes methods
for visualization and supports interactive exploration through integrated
Shiny applications.
