model 
\argModel . Or a list of such models. Tit gives the covariance or variogram models that are to be plotted into the same plot as the empirical variogram (and the fitted models)

arguments to be passed to methods; mainly graphical arguments. 
centers
:the bin centres of the spatial distances
empirical
:value of the empirical variogram
var
:the empirical (overall) variance in the data
sd
:standard deviation of the variogram cloud within each bin
n.bin
:number of bins
phi.centers
:centres of the bins with respect to the (first) angle (for anisotropic empirical variograms only)
theta.centers
:centres of the bins with respect to the second angle (for anisotropic empirical variograms in 3D only)
T
:the bin centres of the time axis
vdim
:the multivariate dimension
coordunits
:string giving the units of the coordinates,
see also option coordunits
of RFoptions
.
varunits
:string giving the units of the variables,
see also option varunits
of RFoptions
.
call
:language object; the function call by which the object was generated
method
:integer; variogram (0), covariance (2), madogram (4)
signature(x = "RFempVariog")
: gives a plot of the
empirical variogram, for more details see
plotmethod
.
signature(x = "RFempVariog", y = "missing")
Gives nice
plots of the empirical variogram; handles binning in up to three
spacedimensions and a timedimension, where the empirical variogram
is plotted along lines which are directed according to the
anglecenters given in x@phi.centers
and
x@theta.centers
; arbitrary theoretical model curves
can be added to the plot by using the argument model
.
If no bins are given, i.e. (x@bin=NULL
),
image
plots are generated.
signature(x = "RFempVariog")
:
converts into other formats, only implemented for target class
list
.
signature(x = "RFfit")
: returns the structure
of x
signature(obj =
"RFempVariog")
: generates nice persp
plots
signature(x = "RFfit")
: identical with
show
method
provides a summary
print
returns also an invisible list that is convenient to access.
