C1.gauss-class: Class 'C1.gauss'

In sdray/adegraphics: An S4 Lattice-Based Package for the Representation of Multivariate Data

Class C1.gauss

Description

A class for the creation and display of a numeric score using gauss' curves.

Objects from the Class

C1.gauss objects can be created by calls of the form new("C1.gauss", ...).

The regular usage in this package is to use the s1d.gauss function.

Slots

data

a list containing data or data's name.

• score: the displayed values in the form of a numeric vector, a name or a matching call.

• fac: a factor for score splitting in the form of a vector, a factor, a name or a matching call.

• wt: a vector of weights for score

• 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.C1 class. The specific slots for C1.gauss objects are:

• fill: a logical to yield the gauss curves transparent.

• col: a logical, a color or a colors vector to color labels, rugs, lines and polygons.

• steps: a value for the number of segments used to draw Gauss curves.

stats

a list of internal preliminary calculations. The specific slots for C1.gauss objects are:

• means: the weighted mean calculated for each fac value.

• var: the weighted variance calculated for each fac value.

• gausscurves: the density gauss curve calculated for each fac value.

s.misc

a list of some others internal parameters. The specific slot for C1.gauss objects is:

• rug: an index value indicating where the rugs are drawn

Call

an object of class call

Extends

Class ADEg.C1, directly.
Class ADEg, by class ADEg.C1, distance 2.
Class ADEgORtrellis, by class ADEg.C1, distance 3.
Class ADEgORADEgSORtrellis, by class ADEg.C1, distance 3.

Methods

The methods of the father classes "ADEg.C1" and "ADEg" can be used by inheritance. The specific methods for C1.gauss are:

prepare

signature(object = "C1.gauss"): calls the parent method (prepare for ADEg.C1), modifies some graphical parameters used by default and calculates the Gauss curves according to the numeric score and the values' categories (using weighted mean and standard deviation).

panel

signature(object = "C1.gauss"): draws Gauss curves and level names of each curve.
