ADEg.Tr-class {adegraphics}

Class "ADEg.Tr"

Description

An object of ADEg.Tr class represents triangular coordinates in 2D.

The ADEg.Tr class is a virtual class, i.e. a class which is not possible to create objects but which have heirs. This class inherits from ADEg class and has three son classes : Tr.class, Tr.label, T.match and T.traject.

Objects from the Class

None object of this class can be instantiated.

Slots

data:

a list containing data or data's name.

• dfxyz: the displayed values in the form of a data frame with three columns, a name or a matching call.

• frame: a positive or null integer. It is the number of the frame containing the data (used with sys.frame(..., env = data$frame)). Only if the data are not stored (i.e. data$storeData = FALSE).

• storeData: a logical indicating if the data should be stored in the returned object. If FALSE, only the names of the data arguments are stored.

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 of two elements to create the trellis object:

• graphictype: xyplot

• arguments: its parameters to obtain the trellis object

g.args

a list containing some method parameters linked with the created object of ADEg.Tr class:

• max3d and min3d: triangular limits

• adjust: a logical to adjust the device with the limits

stats

a list of internal preliminary calculations

s.misc

a list of some others internal parameters:

• adjust.update: a logical indicating if the adjust slot is updating

• cornerp: coordinates of the triangle extremities.

• lgrid: a list containing the three coordinates of the grid segments extremities(pts1, pts2, pts3) and the value of the division (posgrid)

Call

an object of class call

Extends

Class ADEg, directly.

Methods

prepare

signature(object = "ADEg.Tr"): performs the calculations before display the object (e.g. limits, grid and axis calculations)

setlatticecall

signature(object = "ADEg.Tr"): prepares the lattice.call slot

panelbase

signature(object = "ADEg.Tr"): defines the graphical background (e.g. triangle and grid)

gettrellis

signature(object = "ADEg.Tr"): converts the graphic into a trellis object of lattice class
