S2.value
A class for the creation and display of bi-dimensional plot with a third value represented (as a variable) by symbols.
S2.value
objects can be created by calls of the form new("S2.value", ...)
.
The regular usage in this package is to use the s.value
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.
z
: a vector (or a matrix) with as many values as rows in 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.
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.value
objects are:
method
: the method of representation for z
(color shading or proportional size).
symbol
: the type of symbol (square or circle).
center
: a center value for method size
.
centerpar
: a logical or a list to represent center value using elements in the
adegpar("ppoints")
list.
breaks
: a vector containing the breaks used for splitting z
value. If NULL
, pretty(z, n)
is used.
nclass
: an integer for the number of desired intervals, ignored if breaks
is not missing.
col
: a NULL
value, a color or a colors vector to color symbols.
stats
a list of internal preliminary calculations
s.misc
a list of some others internal parameters:
plegend.update
: a logical indicating if the legend parameters are updating
breaks.update
: a logical indicating if the legend breaks are updating
lim.update
: a logical indicating if the limits are updating
Call
an object of class call
Class ADEg.S2
, directly.
Class ADEg
, by class ADEg.S2
, distance 2.
Class ADEgORtrellis

The methods of the father classes "ADEg.S2"
and "ADEg"
can be used by inheritance.
The specific methods for S2.value
are:
signature(object = "S2.value")
:
calls the parent method (prepare
for ADEg.S2
), modifies some graphical parameters used by default and calculates limits.
signature(object = "S2.value")
:
draws symbols.
