# lines.variomodel.variofit

##### Adds a Line with a Fitted Variogram Model to a Variogram Plot

This function adds a line with the variogram model
fitted by the function
`variofit`

to a current variogram plot.

##### Usage

```
# S3 method for variofit
lines.variomodel(x, max.dist, scaled = FALSE, …)
```

##### Arguments

- x
an object of the class

`variofit`

which is a list containing information about the fitted model parameters, typically an output of the function`variofit`

.- max.dist
maximum distance (x-axis) to compute and draw the line representing the variogram model. The default is the distance given by

`x$max.dist`

.- scaled
logical. If

`TRUE`

the total sill in the plot is set to \(1\).- …
arguments to be passed to the function

`curve`

.

##### Details

Adds fitted variogram model to a plot.
In conjuction with `plot.variogram`

can be
used to compare empirical variograms against fitted models returned by
`variofit`

.

##### Value

A line with a variogram model is added to a plot on the current graphics device. No values are returned.

##### Examples

```
# NOT RUN {
# compute and plot empirical variogram
vario <- variog(s100, max.dist = 1)
plot(vario)
# estimate parameters
vario.wls <- variofit(vario, ini = c(1, .3), fix.nugget = TRUE)
# adds fitted model to the plot
lines(vario.wls)
# }
```
