S2.arrowA class for creating and drawing bi-dimensional plot with arrows from the origin to the coordinates and labeled.
S2.arrow objects can be created by calls of the form new("S2.arrow", ...).
The regular usage in this package is to use the s.arrow function.
dataa list containing data or data's name.
dfxy: the displayed values in the form of a data frame, a name or a matching call.
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.
labels: a vector containing the arrows' 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.para list of parameters for lattice call.
It will be passed directly to par.settings arguments of the lattice function.
adeg.para list of graphical parameters, corresponding to the ones
given by adegpar() function.
lattice.calla list to create the trellis object.
g.argsa list containing some method parameters linked with the created object of ADEg.S2 class.
The specific slot for S2.arrow objects is:
Sp: a spatial object stem from Sp package.
statsa list of internal preliminary calculations
s.misca list of some others internal parameters:
lim.update: a logical indicating if the limits are updating
Callan 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.arrow are:
signature(object = "S2.arrow"):
calls the parent method (prepare for ADEg.S2), modifies some graphical parameters used by default and calculates limits.
signature(object = "S2.arrow"):
draws points, arrows and labels.
