S2.class
A class for group representation in bi-dimensional plot.
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.
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 logical or a vector of colors that apply to 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 call
Class ADEg.S2
, directly.
Class ADEg
, by class ADEg.S2
, distance 2.
Class ADEgORtrellis
, by class ADEg.S2
, distance 3.
Class ADEgORADEgSORtrellis
, by class ADEg.S2
, distance 3.
The methods of the father classes "ADEg.S2"
and "ADEg"
can be used by inheritance.
The specific methods for S2.class
are:
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.
signature(object = "S2.class")
:
draws ellipses, convex hulls, stars, labels and points.
