model.cvv {RGeostats}R Documentation

Average covariance within a 2-D Polygon or a generic Cell

Description

Calculate the average covariance within a 2-D Polygon or a generic Cell

Usage

model.cvv(polygon=NA, v.mesh=NA, model = model.input(), 
angles = NA, ivar = 1, jvar = 1, ndisc = 5, seed=321231)

Arguments

polygon

Name of the polygon-class which contains the characteristics of the Polygon. If not defined, the argument 'v.mesh' must be specified instead.

v.mesh

Extension of the generic cell. The length of this argument should be equal to the space dimension as specified in the Model. If this argument is a constant value, the generic cell is generated automatically with this extension along each dimension. If not defined, the argument 'polygon' must be defined instead.

model

Name of the model-class which contains the characteristics of the Model

angles

Array giving the rotation angles (only for dimension 2 or 3). The first angle corresponds to the rotation around OZ axis, the second to a rotation around OY'and the third one around Ox". The dimension of this array cannot exceed the space dimension. This rotation is only taken into account when the volume extension is specified as a generic cell ('v.mesh' argument): it is ignored in the case of a polygon.

ivar

Index of the first field

jvar

Index of the second field

ndisc

Number of discretization steps

seed

Seed used for the generation of random numbers. When 0, the seed is not initialized.

Value

Average covariance value
