RMnatsc

Natural scale

Description

RMnatsc is a stationary isotropic covariance model that depends on a stationary isotropic covariance model phi. The covariance is given by

C(h) = phi(h / s),

where the argument s is chosen by RMnatsc such that the practical range or the mathematical range, if finite, is 1.

Usage

RMnatsc(phi, var, scale, Aniso, proj)

Arguments

`phi`	a stationary isotropic covariance `RMmodel`.
`var,scale,Aniso,proj`	optional arguments; same meaning for any `RMmodel`. If not passed, the above covariance function remains unmodified.

Details

For internal use only.

Value

RMnatsc 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 <- RMnatsc(RMexp())
x <- seq(0, 10, 0.02)
plot(RMexp(), model=model)
RFcov(model, 1)
