Tuple: Mathematical Tuple

Description

A general Tuple object for mathematical tuples, inheriting from Set.

Value

R6 object of class Tuple inheriting from Set.

Constructor

Tuple$new(..., universe = NULL)

Constructor Arguments

Argument	Type	Details
...	ANY	Elements in the tuple.

Constructor Details

Tuples are constructed by elements of any types (including R6 classes). The optional universe argument is useful for taking the absolute complement of the Tuple. If a universe isn't given then Reals is assumed.

Details

Tuples are similar to sets, except that they drop the constraint for elements to be unique, and ordering in a tuple does matter. Tuples are useful for methods including contains that may require non-unique elements. They are also the return type of the product of sets. See examples.

Examples

# NOT RUN {
# Tuple of integers
Tuple$new(1:5)

# Tuple of multiple types
Tuple$new("a", 5, Set$new(1), Tuple$new(2))

# Each Tuple has properties and traits
t = Tuple$new(1,2,3)
t$traits
t$properties

# Elements can be duplicated
Tuple$new(2, 2) != Tuple$new(2)

# Ordering does matter
Tuple$new(1, 2) != Tuple$new(2, 1)
