plot.variog4
Plot Directional Variograms
This function plot directional variograms computed by the function
variog4. The omnidirectional variogram can be also included
in the plot.
Usage
# S3 method for variog4
plot(x, omnidirectional=FALSE, same.plot=TRUE, legend = TRUE, …)Arguments
- x
an object of the class
variog4, typically an output of the functionvariog4.- 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 arecol,lty,lwd. Forsame.plot = TRUEthe arguments are passed to the functionmatplotwhich is used to produce the plot.
Value
A plot is produced on the output device. No values returned.

Examples
# NOT RUN {
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)
