In gmGeostats: Geostatistics for Compositional Analysis

Recast empirical variogram to format logratioVariogram

Description

Recast an empirical compositional variogram of any sort to a variation-variogram of class "logratioVariogram".

Usage

## S3 method for class 'gstatVariogram'
as.logratioVariogram(
  vgemp,
  V = NULL,
  tol = 1e-12,
  orignames = NULL,
  symmetrize = FALSE,
  ...
)

as.logratioVariogram(vgemp, ...)

## S3 method for class 'logratioVariogram'
as.logratioVariogram(vgemp, ...)

## S3 method for class 'gmEVario'
as.logratioVariogram(vgemp, ...)

Arguments

vgemp	empirical variogram
V	matrix or name of the logratio transformation used
tol	tolerance for generalized inverse (eventually for clr case; defaults to 1e-12)
orignames	names of the original component (default NULL)
symmetrize	do you want a whole circle of directions? (default FALSE)
...	parameters for generic functionality

Value

the same model in the new format.

Methods (by class)

• gstatVariogram: method for gstatVariogram objects

• logratioVariogram: identity method

• gmEVario: method for gmEVario objects (not yet available)
