Introduction

This file allows descovering the various models implemented in RGeostats.

library(RGeostats)

In the next paragraph, we define the main global parameters.

Note that not all models are available in all cases: there are usage limitation due to space dimension or degree of the Intrinsic Random Function.

  ndim <- 2
  nvar <- 1

The next paragraph consists of a loop on the different models representing each one of them separately in a normalized manner. For those which accept a third parameter, its value is arbitrarily fixed to 1.2.

                                        # List of the authorized structures #
  list    <- melem.name(degree=0)
  nstruct <- length(list)
  param   <- 1.2
  sill    <- 1

                                        # Loop on the authorized structures #
  for (rank in 1:nstruct) {
    vartype  <- list[rank]
    res      <- melem.characteristics(vartype,ndim=ndim)
    if (res$flag.param && param > res$parmax) param = res$parmax
