RMnatsc: Natural scale
In RandomFields: Simulation and Analysis of Random Fields

Description Usage Arguments Details Value See Also Examples

RMnatsc is a stationary isotropic covariance model that depends on a stationary isotropic covariance model phi. The covariance is given by

C(h) = phi(h / s),

where the argument s is chosen by RMnatsc such that the practical range or the mathematical range, if finite, is 1.

1	RMnatsc(phi, var, scale, Aniso, proj)

`phi`	a stationary isotropic covariance `RMmodel`.
`var,scale,Aniso,proj`	optional arguments; same meaning for any `RMmodel`. If not passed, the above covariance function remains unmodified.

For internal use only.

RMnatsc returns an object of class RMmodel.
