EmpiricalStructuralFunctionSpecification-class {gmGeostats}

Empirical structural function specification

Description

Abstract class, containing any specification of an empirical variogram (or covariance function, or variations). Members must implement a coercion method to class "gmEVario" (see gsi.EVario2D() for an example), and (possibly) coercion to class "gstatVariogram" (see gstat::variogram())
