plotvariogram: Plot theoretical variogram

In rcosmo: Cosmic Microwave Background Data Analysis

Description

Plots theoretical variogram functions from the list defined in covmodelCMB

Usage

plotvariogram(
  cov.model = "matern",
  sigmasq = 1,
  phi = pi,
  kappa = 0.5,
  from = 0,
  to = pi,
  ...
)

Arguments

cov.model	A type of the variogram function. Available choices are: "matern", "exponential","spherical", "powered.exponential", "cauchy", "gencauchy", "pure.nugget", "askey", "c2wendland", "c4wendland", "sinepower", "multiquadric". The default is "matern"
sigmasq	The variance parameter as documented in covmodelCMB. The default is 1.
phi	The range parameter as documented in covmodelCMB. The default is pi.
kappa	A smoothness parameter of the variogram function. The default is 0.5.
from	A lower range of the plotting region. The default is lb =0
to	An upper range of the plotting region. The default is ub= pi.
...	optional plotting parameters.

Value

Produces a plot with the theoretical variogram.
