### Description

Methods for fitted ARMA model objects.

### Usage

    ## S3 method for class 'arma'
    coef(object, ...)
    ## S3 method for class 'arma'
    vcov(object, ...)
    ## S3 method for class 'arma'
    residuals(object, ...)
    ## S3 method for class 'arma'
    fitted(object, ...)
    ## S3 method for class 'arma'
    print(x, digits = max(3, getOption("digits") - 3), ...)
    ## S3 method for class 'arma'
    plot(x, ask = interactive(), ...)

### Arguments

`object, x` | an object of class `"arma"`; usually, a result of a call to `arma`.
`digits` | see `printCoefmat`.
`ask` | Should the `plot` method work interactively? See `interactive`.
`...` | further arguments passed to or from other methods.

### Value

For `coef`, a numeric vector; for `vcov`, a numeric matrix; for `residuals` and `fitted` a univariate time series; for `plot` and `print`, the fitted ARMA model object.
