Union of Sets
Returns the union of objects inheriting from class Set.
setunion(..., simplify = TRUE) ## S3 method for class 'Set' x + y ## S3 method for class 'Set' x | y
The union of N sets, X1, ..., XN, is defined as the set of elements that exist in one or more sets,
U = {x : x ε X1 or x ε X2 or ... or x ε XN}
The union of multiple ConditionalSets is given by combining their defining functions by an
'or', |, operator. See examples.
The union of fuzzy and crisp sets first coerces fuzzy sets to crisp sets by finding their support.
An object inheriting from Set containing the union of supplied sets.
