## Adds Envelopes Lines to a Variogram Plot

### Description

Variogram envelopes computed by `variog.model.env` or `variog.mc.env` are added to the current variogram plot.

### Usage

    ## S3 method for class 'variogram.envelope':
    lines(x, lty = 3, ...)

### Arguments

`x` | an object of the class `"variogram.envelope"`, typically an output of the functions `variog.model.env` or `variog.mc.env`.
`lty` | line type. Defaults to 3.
`...` | arguments to be passed to the function `lines`.

       model = s100.ml)
    s100.mc.env <- variog.mc.env(s100, obj.variog = s100.vario)
    plot(s100.vario)
    lines(s100.mod.env)
    lines(s100.mc.env, lwd=2)
