RFfctn: Evaluate Covariance and Variogram Functions

In RandomFields: Simulation and Analysis of Random Fields

Description

RFfctn returns the values of a shape function.

Usage

RFfctn(model, x, y = NULL, z = NULL, T = NULL, grid, params, distances, dim,...)

Arguments

model,params	\argModel
x	\argX
y,z	\argYz
T	\argT
grid	\argGrid
distances,dim	\argDistances
...	\argDots

Details

RFcovmatrix also allows for variogram models. Then the negative of the variogram matrix is returned.

Value

RFfctn returns a vector.

Examples

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

model <- RMexp() - 1
RFfctn(model, 1:10)
