ciu.to.CIU: Create 'CIU' object from 'ciu' object.

In ciu: Contextual Importance and Utility

Create CIU object from ciu object.

Description

A CIU object is an "object-oriented programming" object, i.e. it has its own environment, private variables and methods etc. A CIU object is created using ciu.new like ciu_obj <- ciu.new(...) and the object's methods are then called as ciu_obj$method(...). This approach has numerous advantages but CIU objects consume much more memory than "ordinary" R data structures.

Usage

ciu.to.CIU(ciu)

Arguments

ciu	ciu object.

Details

A ciu object is simply a list that contains all the "object variables" of a CIU object, which is the reason why CIU <-> ciu conversions can be done at any time. CIU -> ciu conversion doesn't have any overhead but ciu -> CIU does require overhead due to the environment setup etc. Therefore, it is advisable to avoid unnecessary CIU -> ciu conversions.

ciu objects are very memory-efficient because they are ordinary list objects (however, make sure that ciu$CIU element's value is NULL). ciu objects also give direct access to all the object variables that are private in a CIU object.

However, using ciu objects means that they have to be passed as a parameter to all functions that use them. The advantages of object oriented programming are of course lost too.

Value

CIU object
