plot.variogram.SpATS | R Documentation |
Takes a fitted variogram.SpATS
object produced by variogram.SpATS()
and plots the associated sample variogram using an RGL 3D perspective plot (package plot3Drgl
).
## S3 method for class 'variogram.SpATS'
plot(x, min.length = 30, ...)

further arguments passed to or from other methods. Not yet implemented. |
This function as well as function variogram.SpATS()
can only be used for regular two dimensional data.
