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 class 'SpatialPointsDataFrame':
variog(geodata, formula, \ldots)
## S3 method for class 'default':
variogMcEnv(geodata, \ldots)
## S3 method for class 'SpatialPointsDataFrame':
variogMcEnv(geodata, formula, \ldots)

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.

Examples

data("swissRain")
swissRain$lograin = log(swissRain$rain)
swissv= variog(swissRain, formula=lograin ~ 1,option="bin")

if(!is.null(swissv)){
	plot(swissv, env=swissEnv, main = "Swiss variogram")
