Description Usage Arguments Value Author(s) References See Also Examples

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

1 2	## S3 method for class 'variogram.envelope' lines(x, lty = 3, ...)

`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`.

Lines defining the variogram envelope are added to the plotin the current graphics device.

variog for variogram computation, variog.model.env and variog.mc.env for computation of variogram envelopes, and lines for the generic function.
