variog: Compute Empirical Variograms and Permutation Envelopes

Description

These are wrappers for variog and variog.mc.env in the geoR package.

Usage

variog(geodata, …)
# S3 method for SpatialPointsDataFrame
variog(geodata, formula, …)
# S3 method for default
variogMcEnv(geodata, …)
# S3 method for SpatialPointsDataFrame
variogMcEnv(geodata, formula, …)

Arguments

geodata

An object of class SpatialPointsDataFrame or of a class suitable for variog in the geoR package.

formula

A formula specifying the response variable and fixed effects portion of the model. The variogram is performed on the residuals.
