RPgauss: Simulation of Gaussian Random Fields

Description

This function is used to specify a Gaussian random field that is to be estimated or simulated. Return an object of class RMmodel.

Usage

RPgauss(phi, loggauss, stationary_only)

Arguments

phi

the RMmodel.

loggauss

logical. If TRUE then a log-Gaussian random field is returned. Default is FALSE.

stationary_only

Logical or NA. Used for the automatic choice of methods.

• TRUE: the simulation of non-stationary random fields is refused. In particular, the intrinsic embedding method is excluded and the simulation of Brownian motion is rejecte

Value

• The function returns an object of class RMmodel.
