Description Objects from the Class Slots Extends Methods Author(s) See Also Examples

A class for group representation in triangular plot.

`Tr.class`

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

.

The regular usage in this package is to use the `triangle.class`

function.

`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.`fac`

: a factor partitionning the rows of`dfxyz`

.`wt`

: a vector of weights for`fac`

.`labels`

: a vector containing the class' labels.`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:`ellipseSize`

: a positive number for ellipse size.`starSize`

: a number between 0 and 1 for star size.`chullSize`

:`NULL`

or a vector of numbers between 0 and 1 for the convex hulls.`col`

: a`NULL`

value, a color or a colors vector to color points, ellipses, labels, lines and polygons.`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. The specific slots for

`S2.class`

objects are:`means`

: a matrix containing the weighted mean calculated for each`fac`

value.`mean2d`

: a matrix containing the weighted mean calculated for each`fac`

value on two-dimension.`covvar`

: a list containing the weighted variance-covariance matrices calculated for each`fac`

value.`covvar2d`

: a list containing the weighted variance-covariance matrices calculated for each`fac`

value on two-dimension.

`s.misc`

a list of some others internal parameters:

`ellipses`

: ellipses' coordinates.`chullcoord`

: convex hulls' coordinates.

`Call`

an object of class

`call`

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.

The methods of the father classes `"ADEg.Tr"`

and `"ADEg"`

can be used by inheritance.
The specific methods for `Tr.class`

are:

- prepare
`signature(object = "Tr.class")`

: calls the parent method (`prepare`

for`ADEg.Tr`

), modifies some graphical parameters used by default and calculates ellipses, convex hulls and centroids.- panel
`signature(object = "Tr.class")`

: draws arrows, labels and points.
