Class "melem" Basic Structure

Description

Basic structure

Objects from the Class

Objects can be created by calls of the form new("melem", ...). Basic structure

Slots

vartype:

Object of class "character" Type of the basic structure. This argument must be chosen among:

  • 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 structures are not available for covariances. Please refer to RGeostats User Manual for each basic structure equation.

sill:

Object of class "matrix" Array of sills (or slopes)

range:

Object of class "numeric" Range

param:

Object of class "numeric" Third parameter

flag.aniso:

Object of class "logical" Specify if the anisotropy must be defined

aniso.rotmat:

Object of class "matrix" Rotation matrix defining the main axes of the anisotropy ellipsoid

aniso.coeffs:

Object of class "matrix" Matrix of coefficients that divide the (isotropic) range along the main axes of the anisotropy ellipsoid

Methods

\$

melem$parameter is used to query the value of parameter from melem:

  • vartype : Type of the covariance or variogram

  • sill : Array of sills

  • range : Range value

  • flag.aniso : 1 if the basic structure is anisotropic

  • aniso.rotmat : Rotation matrix defining the main axes of the anisotropy ellipsoid

  • aniso.coeffs : Matrix of anisotropy ratio
