R: Creating poylonmial models

RMpolynome {RandomFields} | R Documentation

## Creating poylonmial models

### Description

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

### Usage

    RMpolynome(degree, dim, value=NA, varnames = 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
`varnames` | the names of the variables
`proj` | the projection to certain dimensions.

### Details

If the length of `value` is smaller than the number of mononomes, the remaining terms are filled with `NA`s. If the length is larger, the vector is cut.

### Value

`RMpolynome` returns an object of class `RMmodel`.
