T.value-class {adegraphics}R Documentation

Class T.value

Description

A class for the representation of a matrix, a data frame, or a distance matrix using symbols, varying in size or color.

Objects from the Class

T.value objects can be created by calls of the form new("T.value", ...).

The regular usage in this package is to use the table.value function.

Slots

data:

a list containing data or data's name.

trellis.par

a list of parameters for lattice call. It will be passed directly to par.settings arguments of the lattice function.

adeg.par

a list of graphical parameters, corresponding to the ones given by adegpar() function.

lattice.call

a list to create the trellis object.

g.args

a list containing some method parameters linked with the created object of ADEg.T class. The specific slots for T.value objects are:

stats

a list of internal preliminary calculations

s.misc

a list of some others internal parameters:

Call

an object of class call

Extends

Class ADEg.T, directly.
Class ADEg, by class ADEg.T, distance 2.
Class ADEgORtrellis, by class ADEg.T, distance 3.
Class ADEgORADEgSORtrellis, by class ADEg.T, distance 3.

Methods

The methods of the father classes "ADEg.T" and "ADEg" can be used by inheritance. The specific methods for T.value are:

prepare

signature(object = "T.value"): calls the parent method (prepare for ADEg.T) and modifies some graphical parameters used by default and calculates limits and grid.

panel

signature(object = "T.value"): draws symbols.

Note

For the symbol size, if the method is size, we use perceptual scaling (Tanimura et al. 2006) .
