Plot a 'gv' object

Description

Plot the semi-variogram in a gv object. If a multiple genetic distances are found, it plots the median value and the 95% confidence interval for the median.

Usage

## S3 method for class 'gv'
plot(x, line.res = 100, pch=1, legend=TRUE, leg.x=NA, leg.y=NA, 
                  leg.cex=1, ...)

Arguments

x

'gv' object as given by 'gen.variogram'.

line.res

Number of points in the model line.

pch

Symbol to be used in the plot.

legend

Boolean indicating if a legend showing n size should be printed.

leg.x

The x position for the legend. The legend will be placed at the right side of the plot if this value is set to NA.

leg.y

The y position for the legned. The legend will be placed at the bottom of the plot if this value is set to NA.

leg.cex

Multiplication factor for the legend symbol size.

...

Further plotting arguments to be passed.

Details

Simple plot of the semi-variogram contained in a 'gv' object. If the object has a model, the model line is also plotted.

Value

Plot.
