ADEg.Tr-class: 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
