Set Operations
Provides the generic functions and the S4 methods for the set operations
union, intersect, setequal, setdiff and
is.element on sets of associations (e.g., rules, itemsets) and
itemMatrix.
union(x, y) intersect(x, y) setequal(x, y) setdiff(x, y) is.element(el, set)
x,y, el, set |
sets of associations or itemMatrix objects. |
All S4 methods for set operations are defined for the
class name "ANY" in the signature,
so they should work for all S4 classes for which the following
methods are available: match, length and unique.
union, intersect, setequal and setdiff return an
object of the same class as x and y.
is.element returns a logic vector of length el indicating
for each element if it is included in set.
