associations-class {arules} | R Documentation |
The associations
class is a virtual class which is extended to
represent mining result (e.g., sets of itemsets or rules). The class
provides accessors for the quality slot and a method for sorting the
associations.
A virtual class: No objects may be created from it.
quality
:data.frame
for quality
measures (e.g., interest measures as support or confidence). Each
quality measure is a named vector with the same length as the
number of elements in the set of associations and each vector
element belongs to the association with the same index.signature(x = "associations")
;
sorts the associations by a quality measure specified as the
argument by
(default: by = "support", decreasing =
TRUE
).signature(x = "associations")
;
replaces the quality data.frame
. The length of the vectors
in the data.frame
has to equal the number of associations
in the set.signature(x = "associations")
;
returns the quality data.frame
.signature(object = "associations")
