variog: Compute Empirical Variograms and Permutation Envelopes

In geostatsp: Geostatistical Modelling with Likelihood and Bayes

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, ...)
## Default S3 method:
variogMcEnv(geodata, ...)
## S3 method for class '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.
...	additional arguments passed to variog in the geoR package.

Value

As variog or variog.mc.env

See Also

variog and variog.mc.env.

Examples

data("swissRain")
swissRain$lograin = log(swissRain$rain)
swissv= variog(swissRain, formula=lograin ~ 1,option="bin")
swissEnv = variogMcEnv(swissRain, lograin ~ 1, obj.var=swissv,nsim=9) 
if(!is.null(swissv)){
	plot(swissv, env=swissEnv, main = "Swiss variogram")
}
