set6
upgrades the sets
package to R6. Many forms of mathematical sets are implemented, including (countably finite) sets, tuples, intervals (countably infinite or uncountable), and fuzzy variants. Wrappers extend functionality by allowing symbolic representations of complex operations on sets, including unions, (cartesian) products, exponentiation, and differences (asymmetric and symmetric).set6
is currently ‘maturing’, so whilst no major updates are planned they may happen. Constant minor updates should be expected.
