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.
