design_matrix {BPRMeth} | R Documentation

## Generic function for creating design matrices

### Description

These functions call the appropriate methods depending on the class of the object `obj` to create RBF, polynomial or Fourier design matrices.

### Usage

    design_matrix(obj, ...)

    ## Default S3 method:
    design_matrix(obj, ...)

    ## S3 method for class 'polynomial'
    design_matrix(obj, obs, ...)

    ## S3 method for class 'rbf'
    design_matrix(obj, obs, ...)

    ## S3 method for class 'fourier'
    design_matrix(obj, obs, ...)

### Arguments

`obj` | A basis function object.
`...` | Additional parameters.
`obs` | A vector of observations.

### Value

A design matrix object
