model-class {RGeostats} | R Documentation |
This Class contains the geostatistical "structure" (variogram or
covariance) which describes the regularity of one variable or several
variables. It may contain one or several Basic Structure
(melem-class
).
Objects can be created by calls of the form new("model", ...)
.
Geostatistical Model
ndim
:Object of class "numeric"
Space dimension
nvar
:Object of class "numeric"
Number of variables
basics
:Object of class "list"
List of basic structures of
melem-class
properties
:A list
where the user can define the parameters of
the transformation applied to the Model.
model[i]
returns the melem-class
containing the
basic structure number i
.
model[i]<-value
copies the contents of the value
into the i-th
basic structure of the model-class
model$parameter
is used to query the value of
parameter
from model
:
ndim : Space dimension
nvar : Number of variables
ncova : Number of basic structures
basics : List of the basic structures
Same as above but for assignment
Other functions are available, such as:
model.auto

for a set of distances, specified by
their increments.

model-class
into a multivariate one
