ADEg.C1-class: Class 'ADEg.C1'

Description Objects from the Class Slots Extends Methods Note Author(s) See Also Examples


An object of ADEg.C1 class represents unidimensional data into two dimensions.

The ADEg.C1 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 : C1.barchart, C1.curve, C1.density, C1.dotplot, C1.gauss, C1.hist, C1.interval

Objects from the Class

None object of this class can be instantiated.



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.

  • 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.


a list of parameters for lattice call. It will be passed directly to par.settings arguments of the lattice function.


a list of graphical parameters, corresponding to the ones given by adegpar() function.

a list of two elements to create the trellis object:

  • graphictype: xyplot

  • arguments: its parameters to obtain the trellis object


a list containing some method parameters linked with the created object of ADEg.C1 class


a list of internal preliminary calculations


a list of some others internal parameters:

  • hori.update: a logical indicating if the sense of direction of the graphics is updating

  • backgrid: a list of two elements for grid lines. backgrid$x defines the coordinates of the lines (horizontal or vertical depending on the graphics orientation) and backgrid$d the grid mesh


an object of class call


Class ADEg, directly.



signature(object = "ADEg.C1"): performs the calculations before display the object (e.g. limits, grid and axis calculations)


signature(object = "ADEg.C1"): prepares the slot


signature(object = "ADEg.C1"): defines the graphical background (e.g. grid, rugs and box)


signature(object = "ADEg.C1"): converts the graphic into a trellis object of lattice class


The ADEg.S1 class and ADEg.C1 class are both used to represent an unidimensional information (e.g. a score). The difference between these two classes is mainly ideological : an ADEg.S1 object is a representation into one dimension (e.g. one line) while an ADEg.C1 object is a representation into two dimensions (e.g. curves).
