Objects from the Class
S2.image objects can be created by calls of the form new("S2.image", ...). The regular usage in this package is to use the s.image 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.
z: a vector (or a matrix) of values on the dfxy rows.
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.image objects are:
gridsize: a 1 or 2-length vector indicating the cell numbers (horizontally and vertically) of the grid for the colored surface.
outsideLimits: specific limits for the surface as a set of polygons. It must be an SpatialPolygons object. Hole are authorized.
span: a value to control the degree of smoothing.
contour: a logical to draw contour lines.
region: a logical to fill inter-contour regions.
col: a NULL value, a color or a colors vector used for the colored cells.
stats- a list of internal preliminary calculations.
The specific slot for
S2.image objects is:
value: a prediction value yielded by a local polynomial regression fitting.
s.misc- a list of some others internal parameters:
newgrid: the grid expansion calculated within the prepare method.
Call- an object of class
call

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