Lattice-class: Class "Lattice"

Description

Class Lattice formalizes an affine linearly generated grid of (support) points pivot + (0:(Length-1)) * width; this is used for subclass LatticeDistribution of class DiscreteDistribution which in addition to the latter contains a slot lattice of class Lattice.

Usage

Lattice(pivot = 0, width = 1, Length = 2, name = "a lattice")

Objects from the Class

Objects may be generated by calling the generating function Lattice.

Arguments

pivot: the (finite) utmost left or right value of the lattice
width: the (finite) grid-width; if negative the lattice is expanded to the left, else to the right
Length: the (possibly infinite) length of the lattice
name: the (possibly empty) name of the lattice (inherited from class rSpace)

Slots

pivot: Object of class "numeric": --- the pivot of the lattice; must be of length 1
width: Object of class "numeric": --- the width of the lattice; must be of length 1 and must not be 0
Length: Object of class "numeric": --- the width of the lattice; must be an integer > 0 of length 1
name: Object of class "character": the name of the space, by default = "a lattice"

Extends

Class "rSpace", directly.

Methods

pivot: signature(.Object = "Lattice"): returns the 'pivot' slot
pivot<-: signature(.Object = "Lattice"): modifies the 'pivot' slot
width: signature(.Object = "Lattice"): returns the 'width' slot
width<-: signature(.Object = "Lattice"): modifies the 'width' slot
Length: signature(.Object = "Lattice"): returns the 'Length' slot
Length<-: signature(.Object = "Lattice"): modifies the 'Length' slot
