is_nugget

Check if the given object is a nugget, i.e. an object created by
<code>nugget()</code>. If a <code>flavour</code> is specified, the function returns <code>TRUE</code> only
if the object is a nugget of the given flavour.

A framework for systematic exploration of
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 also be supplied to guide custom pattern searches.
Supports both crisp (Boolean) and fuzzy data. Generates candidate conditions
expressed as elementary conjunctions, evaluates them on a dataset, and
inspects the induced sub-data for statistical, logical, or structural
properties such as associations, correlations, or contrasts. Includes methods
for visualization of logical structures and supports interactive exploration
through integrated Shiny applications.
