Plot Directional Variograms

Description

This function plot directional variograms computed by the function variog4. The omnidirectional variogram can be also included in the plot.

Usage

## S3 method for class 'variog4'
plot(x, omnidirectional=FALSE, same.plot=TRUE, legend = TRUE, ...)

Arguments

`x`	an object of the class `variog4`, typically an output of the function `variog4`.
`omnidirectional`	logical. Indicates whether the omnidirectional variogram is included in the plot.
`same.plot`	logical. Indicates whether the directional variograms are plotted in the same or separated plots.
`legend`	logical indicating whether legends are automatically included in the plots.
`...`	further arguments to be passed to the function `plot`. Typical arguments are `col`, `lty`, `lwd`. For `same.plot = TRUE` the arguments are passed to the function `matplot` which is used to produce the plot.

Value

A plot is produced on the output device. No values returned.

Examples

s100.v4 <- variog4(s100, max.dist=1)
# Plotting variograms for the four directions
plot(s100.v4)
# changing plot options
plot(s100.v4, lwd=2)
plot(s100.v4, lty=1, col=c("darkorange", "darkblue", "darkgreen","darkviolet"))
plot(s100.v4, lty=1, lwd=2)
# including the omnidirectional variogram
plot(s100.v4, omni=TRUE)
# variograms on different plots
plot(s100.v4, omni=TRUE, same=FALSE)
