RMcauchytbm {RandomFields}

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))
