RMpolynome: Creating polynomial models

In RandomFields: Simulation and Analysis of Random Fields

Description

Polynomials, mainly used in trend models, can be created easily with this function.

Usage

RMpolynome(degree, dim, value=NA, coordnames = c("x", "y", "z", "T"),
           proj=1:4)

Arguments

degree	degree of the polynome
dim	number of variables in the polynome
value	values of the coefficients. See Details.
coordnames	the names of the variables
proj	the projection to certain dimensions

Details

If the length of value is smaller than the number of monomials, the remaining terms are filled with NAs. If the length is larger, the vector is cut.

Value

RMpolynome returns an object of class RMmodel.
