Tr.label-class {adegraphics}

Class Tr.label

Description

A class for creating and drawing triangular plot with point label.

Objects from the Class

Tr.label objects can be created by calls of the form new("Tr.label", ...).

The regular usage in this package is to use the triangle.label function.

Slots

data

a list containing data or data's name.

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

• labels: a character vector containing labels for points.

• 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 to create the trellis object.

g.args

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

• addmean: a logical to plot the mean.

• addaxes: a logical to draw the principal axes.

• meanpar: a list to represent mean points using pch, cex and col.

• axespar: a list to represent axes lines using col, lwd and lty.

• max3d and min3d: vectors of three values for triangular maximal and minimal limits.

• adjust: a logical to adjust the device with the limits of the smaller equilateral triangle containing the values.

stats

a list of internal preliminary calculations

s.misc

a list of some others internal parameters:

• cornerp: coordinates of the triangle extremities.

Call

an object of class call

Extends

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

Methods

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

prepare

signature(object = "Tr.label"): calls the parent method (prepare for ADEg.Tr), modifies some graphical parameters used by default and defines the mean point and the axes.

panel

signature(object = "Tr.label"): draws lines, labels and points.
