"ADEg.Tr"
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
.
None object of this class can be instantiated.
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
Class ADEg
, directly.
signature(object = "ADEg.Tr")
:
performs the calculations before display the object (e.g. limits, grid and axis calculations)
signature(object = "ADEg.Tr")
:
prepares the lattice.call
slot
signature(object = "ADEg.Tr")
:
defines the graphical background (e.g. triangle and grid)
signature(object = "ADEg.Tr")
:
converts the graphic into a trellis
