Default variogram.SpATS plotting

Description

Takes a fitted variogram.SpATS object produced by variogram.SpATS() and plots the associated sample variogram using an RGL 3D perspective plot (package plot3Drgl).

Usage

## S3 method for class 'variogram.SpATS'
plot(x, min.length = 30, ...)

Arguments

x

an object of class variogram.SpATS as produced by variogram.SpATS().

min.length

numerical value. The sample variogram is depicted including only those pairs with more than min.length observations (see variogram.SpATS).

...

further arguments passed to or from other methods. Not yet implemented.

Details

This function as well as function variogram.SpATS() can only be used for regular two dimensional data.

# Compute the variogram
