set6 (version 0.2.4)

UnionSet: Set of Unions

Description

UnionSet class for symbolic union of mathematical sets.

Arguments

Super classes

set6::Set -> set6::SetWrapper -> UnionSet

Active bindings

elements

Returns the elements in the object.

length

Returns the number of elements in the object.

Methods

Public methods

Method new()

Create a new UnionSet object. It is not recommended to construct this class directly.

Usage

UnionSet$new(setlist, lower = NULL, upper = NULL, type = NULL)

Arguments

setlist

list of Sets to wrap.

lower

lower bound of new object.

upper

upper bound of new object.

type

closure type of new object.

Returns

A new UnionSet object.

Method strprint()

Creates a printable representation of the object.

Usage

UnionSet$strprint(n = 2)

Arguments

n

numeric. Number of elements to display on either side of ellipsis when printing.

Returns

A character string representing the object.

Method contains()

Tests if elements x are contained in self.

Usage

UnionSet$contains(x, all = FALSE, bound = FALSE)

Arguments

x

any. Object or vector of objects to test.

all

logical. If FALSE tests each x separately. Otherwise returns TRUE only if all x pass test.

bound

logical.

Returns

If all == TRUE then returns TRUE if all x are contained in self, otherwise FALSE. If all == FALSE returns a vector of logicals corresponding to the length of x, representing if each is contained in self. If bound == TRUE then an element is contained in self if it is on or within the (possibly-open) bounds of self, otherwise TRUE only if the element is within self or the bounds are closed.

Method clone()

The objects of this class are cloneable with this method.

Usage

UnionSet$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.

Details

The purpose of this class is to provide a symbolic representation for the union of sets that cannot be represented in a simpler class. Whilst this is not an abstract class, it is not recommended to construct this class directly but via the set operation methods.
