Class S2.traject — S2.traject-class • adegraphics

A class for the creation of a bi-dimensional plot with trajectories linking the points.

Objects from the Class

S2.traject objects can be created by calls of the form new("S2.traject", ...).

The regular usage in this package is to use the s.traject 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.
labels: a vector of character strings containing the trajectories' labels.
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 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.traject objects are:

order: a vector containing the drawing order of the trajectories. A vector of length equal to factor.
col: a NULL value, a color or a colors vector to color points, labels and lines.

stats

a list of internal preliminary calculations

s.misc

a list of some others internal parameters

Call

an object of class call

Extends

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.

Methods

The methods of the father classes "ADEg.S2" and "ADEg" can be used by inheritance. The specific methods for S2.traject are:

prepare: signature(object = "S2.traject"): calls the parent method (prepare for ADEg.S2) and modifies some graphical parameters used by default.
panel: signature(object = "S2.traject"): draws points, arrows and labels.
