Objects from the Class
S2.class objects can be created by calls of the form new("S2.class", ...). The regular usage in this package is to use the s.class function.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.
fac: a factor (or a matrix of factors) splitting the rows of dfxy.
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.
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.S2 class.
The specific slots for S2.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.
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.
covvar: a list containing the weighted variance-covariance matrices calculated for each fac value.
s.misc- a list of some others internal parameters:
ellipses: ellipses' coordinates.
chullcoord: convex hulls' coordinates.
Call- an object of class

Class ADEgORADEgSORtrellis, by class ADEg.S2, distance 3.Methods
The methods of the father classes "ADEg.S2" and "ADEg" can be used by inheritance.
The specific methods for S2.class are:
- prepare
signature(object = "S2.class"):
calls the parent method (prepare for ADEg.S2), modifies some graphical parameters used by
default and calculates ellipses, convex hulls and centroids.- panel
signature(object = "S2.class"):
draws ellipses, convex hulls, stars, labels and points.
