ADEg.S2-class: Class ADEg.S2
Description
An object of ADEg.S2 class represents bi-dimensional data.
The ADEg.S2 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 eleven son classes : S2.arrow, S2.class, S2.corcircle, S2.density, S2.distri,
S2.image, S2.label, S2.logo, S2.match, S2.traject and S2.value.
Objects from the Class
None object of this class can be instantiated.Slots
data- a list containing data or data's name.
dfxy: the displayed values in the form of a data frame, a name or a matching call.
xax: an integer or a vector indicating the columns of dfxy kept for the x-axes.
yax: an integer or a vector indicating the columns of dfxy kept for the y-axes.
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.S2 class:
fullcircle: only for S2.corcircle objects
method: only for S2.value objects
symbol: only for S2.value objects
center: only for S2.value objects
stats- a list of internal preliminary calculations
s.misc- a list of some others internal parameters:
xfullcircle.update and yfullcircle.update: a logical indicating if the circle size is updating (only for S2.corcircle objects)
plegend.update: a logical indicating if the legend parameters are updating
breaks.update: a logical indicating if the legend breaks are updating
backgrid: a list of elements for grid lines
Call- an object of class
call
Extends
Class ADEg, directly.Methods
- prepare
signature(object = "ADEg.S2"):
performs the calculations before display the object (e.g. limits, grid and axis calculations)- setlatticecall
signature(object = "ADEg.S2"):
prepares the lattice.call slot- panelbase
signature(object = "ADEg.S2"):
defines the graphical background (e.g. grid and box)- gettrellis
signature(object = "ADEg.S2"):
converts the graphic into a trellis object of lattice class- zoom
signature(object = "ADEg.S2", zoom = "numeric", center = "missing"):
performs a zoom in (if zoom < 1) or out (if zoom > 1) centered- zoom
signature(object = "ADEg.S2", zoom = "numeric", center = "numeric"):
performs a zoom in (if zoom < 1) or out (if zoom > 1) around the center passed in parameter (center should be a two-length vector)- addhist
signature(object = "ADEg.S2"):
adds histograms and density lines against a bi-dimensional graphics
