The db-class (organized as a set of isolated points) containing the variables used for the calculation the Variogram Map.

The db-class (organized as a grid) which will contain the Variogram Map results. If not provided, the 'dbmap' file is created by this procedure. Otherwise the results of this calculation will be added as new variables.

Gives the dimension of the Variogram Map along the first axis (2*nx+1)

Gives the dimension of the Variogram Map along the second axis (2*ny+1)

Gives the mesh of the Variogram Map along the first axis. If not provided, it is calculated as proportion of the field elongation along the first direction.

Gives the mesh of the Variogram Map along the second axis. If not provided, it is calculated as proportion of the field elongation along the second direction.

Character string giving the type of structure to compute:

• vg : Variogram

• cov : Covariance (Centered)

• covnc : Non-centered Covariance

• covg : Transitive Covariogram

• mado : Madogram (Variogram of order 1)

• rodo : Rodogram (Variogram of order 1/2)

• poisson : Variogram of a Poisson-weighted variable

Dilation radius. Each pair of points contributes to the value of a target cell (with respect to the distance between the two end-points). When the radius is positive, this pair also contributes to a set of other cells, all of them lying within a dilated area around the target cell. This argument gives the extension of this dilation: e.g. a radius of 0 corresponds to the traditional variogram map calculation.

Radix of the name given to the variables stored in the Variogram Map Grid

Decides whether or not the newly created variables will have their locator defined or not. For more information, see db.locmod.
