R: Update an lmRob Model Object

update.lmRob {robust} | R Documentation

## Update an lmRob Model Object

### Description

A method for the generic `update` function for objects inheriting from class `lmRob`. See `update` for the general behavior of this function and for the interpretation of the arguments.

### Usage

    ## S3 method for class 'lmRob'
    update(object, formula., ..., evaluate = TRUE)

### Arguments

`object` | an lmRob object.
`formula.` | a modeling formula, such as `y ~ a + b`. A single dot `.` on either side of the `~` gets replaced by the left or right side of the formula in `object`. The dot on the left can be omitted. By default, it refits object using the same formula as in `object`.
`evaluate` | a logical value. If `TRUE` the updated call is evaluated and returned. Otherwise the unevaluated call is returned.
`...` | additional arguments passed to the generic update function.

### Details

If `formula.` is missing, `update.lmRob` alternates between the initial estimates and final estimates. Otherwise (when `formula.` is present), `update.lmRob` functions just like `update.default`.

### Value

either a new updated object, or else an unevaluated expression for creating such an object.

### See Also
