RMcauchytbm: 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, if (interactive()) 0.02 else 1) 
plot(model)
plot(RFsimulate(model, x=x))
