lines.variogram.envelope: 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

lines.variogram.envelope(obj, lty = 3, ...)

Arguments

obj

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.

Value

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