\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
plot-method
.
signature(x = "RFempVariog", y = "missing")
Gives nice
plots of the empirical variogram; handles binning in up to three
space-dimensions and a time-dimension, where the empirical variogram
is plotted along lines which are directed according to the
angle-centers 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.
