In geoR: Analysis of Geostatistical Data

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.
