R: Auxiliary support for the GAMLSS

polyS {gamlss} | R Documentation

## Auxiliary support for the GAMLSS

### Description

These two functions are similar to the `poly` and `polym` in R. Are needed for the `gamlss.lo` function of GAMLSS and should not be used on their own.

### Usage

    polyS(x, ...)
    poly.matrix(m, degree = 1)

### Arguments

`x` | a variable
`m` | a variable
`degree` | the degree of the polynomial
`...` | for extra arguments

### Value

Returns a matrix of orthogonal polynomials

### Warning

Not be use by the user
