S2.density
A class for the creation and display of bi-dimensional plot with density estimation.
S2.density
objects can be created by calls of the form new("S2.density", ...)
.
The regular usage in this package is to use the s.density
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.
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.density
objects are:
bandwidth
: bandwidth for density calculations which is passed in parameters in the bkde2D
function of the KernSmooth
package.
gridsize
: grid dimension.
threshold
: a value between 0 and 1 to draw densities greater than this threshold. No density is visible whether it is equal to 1.
col
: a NULL
value, a color or a colors vector to color densities.
nrpoints
: number of points on the density image.
contour
: a logical to draw contour lines.
region
: a logical to fill grid regions with col
.
nclass
: number of class for density.
stats
a list of internal preliminary calculations.
The specific slot for S2.density
objects is:
densit
: a list containing the results of the bkde2D
function.
s.misc
a list of some others internal parameters
Call
an 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.density
are:
signature(object = "S2.density")
:
calls the parent method (prepare
for ADEg.S2
), modifies some graphical parameters used by default and calculates densities.
signature(object = "S2.density")
:
draws densities and external points.
