plot.variog4 {geoR} | R Documentation

## 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

    if(is.R()) data(s100)
    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)
