melem.characteristics {RGeostats}R Documentation

Returns the characteristics of a basic structure

Description

Returns the characteristics of a basic structure

Usage

melem.characteristics(vartype, ndim = 2, norder = 0)

Arguments

vartype

Type of the Basic Structure to be created. By default, this type corresponds to the Nugget Effect. The list of types available is:

  • Nugget effect

  • Exponential

  • Spherical

  • Cubic

  • Gaussian

  • Cardinal Sine

  • J-Bessel

  • K-Bessel

  • Gamma

  • Cauchy

  • Stable

  • Linear

  • Cosinus (1D)

  • Triangle (1D)

  • Cosine Exponential

  • Exp2dfact

  • Expfact

  • Reg1D (1D)

  • Pentamodel

  • Power

  • Order-1 GC

Some are restricted to 1-D case. The two last types should be discarded when building a covariance Model

ndim

Space dimension

norder

Parameter giving the maximum order of the IRF which corresponds to the model defined. If mode=-1, only covariances can be entered; if mode=0, all covariances and variograms are allowed.

Value

The following information is returned:
