R: Local Design Matrix for a Generalized Nonlinear Model

model.matrix.gnm {gnm} | R Documentation

## Local Design Matrix for a Generalized Nonlinear Model

### Description

This method extracts or evaluates a local design matrix for a generalized nonlinear model

### Usage

    ## S3 method for class 'gnm'
    model.matrix(object, coef = NULL, ...)

### Arguments

`object` | an object of class `gnm`.
`coef` | if specified, the vector of (non-eliminated) coefficients at which the local design matrix is evaluated.
`...` | further arguments.

### Value

If `coef = NULL`, the local design matrix with columns corresponding to the non-eliminated parameters evaluated at `coef(object)` (extracted from `object` if possible).

Otherwise, the local design matrix evaluated at `coef`.
