R Documentation

Modifications of the Cauchy Family Covariance Model

Description

RMcauchytbm() is a shortcut of RMtbm(RMgencauchy()) and is given here for downwards compatibility.

Usage

RMcauchytbm(alpha, beta, gamma, var, scale, Aniso, proj)

Arguments

`alpha,beta`	See `RMgencauchy`.
`gamma`	is the same as `fulldim` in `RMtbm`.
`var,scale,Aniso,proj`	optional arguments; same meaning for any `RMmodel`. If not passed, the above covariance function remains unmodified.

Value

RMcauchytbm returns an object of class RMmodel.

Examples

RFoptions(seed=0) ## *ANY* simulation will have the random seed 0; set
##                   RFoptions(seed=NA) to make them all random again

model <- RMcauchytbm(alpha=1, beta=1, gamma=3)
x <- seq(0, 10, 0.02)
plot(model)
plot(RFsimulate(model, x=x))
