S2.value-class {adegraphics}R Documentation

Class S2.value

Description

A class for the creation and display of bi-dimensional plot with a third value represented (as a variable) by symbols.

Objects from the Class

S2.value objects can be created by calls of the form new("S2.value", ...).

The regular usage in this package is to use the s.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.S2 class. The specific slots for S2.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.S2, directly.
Class ADEg, by class ADEg.S2, distance 2.
Class ADEgORtrellis, by class ADEg.S2, distance 3.
Class ADEgORADEgSORtrellis, by class ADEg.S2, distance 3.

Methods

The methods of the father classes "ADEg.S2" and "ADEg" can be used by inheritance. The specific methods for S2.value are:

prepare

signature(object = "S2.value"): calls the parent method (prepare for ADEg.S2), modifies some graphical parameters used by default and calculates limits.

panel

signature(object = "S2.value"): draws symbols.

Note

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