%description
Implements the Classification-based on Association Rules (CBA) algorithm
for association rule classification. The package, also described in
Hahsler et al. (2019) <doi:10.32614/RJ-2019-048>, contains several
convenience methods that allow to automatically set CBA parameters
(minimum confidence, minimum support) and it also natively handles numeric
attributes by integrating a pre-discretization step. The rule generation
phase is handled by the 'arules' package. To further decrease the size of
the CBA models produced by the 'arc' package, postprocessing by the 'qCBA'
package is suggested.
