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.
