coef.varFunc | R Documentation |

This method function extracts the coefficients associated with the
variance function structure represented by `object`

.

```
## S3 method for class 'varFunc'
coef(object, unconstrained, allCoef, ...)
## S3 replacement method for class 'varIdent'
coef(object, ...) <- value
```

`object` |
an object inheriting from class |

`unconstrained` |
a logical value. If |

`allCoef` |
a logical value. If |

`value` |
a vector with the replacement values for the coefficients
associated with |

`...` |
some methods for this generic require additional arguments. None are used in this method. |

a vector with the coefficients corresponding to `object`

.

On the left side of an assignment, sets the values of the coefficients
of `object`

to `value`

.
