R: Pratical range for correlation functions

practicalRange {geoR} | R Documentation

## Pratical range for correlation functions

### Description

Computes practical ranges for the correlation functions implemented in the geoR package

### Usage

    practicalRange(cov.model, phi, kappa = 0.5, correlation = 0.05, ...)

### Arguments

`cov.model` | correlation model as documented in `cov.spatial`.
`phi` | correlation parameter as documented in `cov.spatial`.
`kappa` | additional correlation parameter as documented in `cov.spatial`.
`correlation` | correlation threshold for asymptotic models. Defaults to 0.05.
`...` | arguments to be passed to `optimise`.

### Value

A scalar with the value of the practical range.

### See Also

`cov.spatial`

### Examples

    practicalRange("exp", phi=10)
    practicalRange("sph", phi=10)
    practicalRange("gaus", phi=10)
    practicalRange("matern", phi=10, kappa=0.5)
    practicalRange("matern", phi=10, kappa=1.5)
    practicalRange("matern", phi=10, kappa=2.5)
