Class "positioned", extends "ordered" to specify the position for graphing the levels of a factor.

Description

The default values for plotting a factor x are the integers 1:length(levels(x)). This class and its functions provide a way of specifying alternate plotting locations for the levels.

Objects from the Class

A virtual Class: No objects may be created from it.

Extends

Class "ordered", directly. Class "factor", by class "ordered", distance 2. Class "oldClass", by class "ordered", distance 3.

Methods

No methods defined with class "positioned" in the signature. S3-type methods are "[.positioned", as.double.positioned, as.numeric.positioned, as.positioned, is.numeric.positioned, is.positioned, positioned, print.positioned, unique.positioned.
Although interaction.positioned should be a method, it isn't because interaction is not a generic and can't easily be made one since the name interaction.plot conflicts.
