## Methods for Function `extract` in Package aws

### Description

The method extract and/or compute specified statistics from object of class `"aws"`, `"awssegment"`, `ICIsmooth` and `"kernsm"`.

### Usage

      ## S4 method for signature 'aws'
    extract(x, what="y")
      ## S4 method for signature 'awssegment'
    extract(x, what="y")
      ## S4 method for signature 'ICIsmooth'
    extract(x, what="y")
      ## S4 method for signature 'kernsm'
    extract(x, what="y")

### Arguments

`x` | object
`what` | Statistics to extract, defaults to `what="y"` corresponding to the original data (response variable). Alternatives are `what="yhat"` for the smoothed response, `what="vhat"` for the estimated variance of the smoothed response, `what="sigma2"` for the estimated error variance of the original data, `what="vred"` for the variance reduction achieved and in case of `signature(x = "ICIsmooth")` `what="hbest"` for the selected bandwidth. A vector of any of these choices may be provided.

### Methods

`signature(x = "ANY")`

  Returns a message that method `extract` is not defined.

`signature(x = "aws")`

  Returns a list with components containing the requested statistics. Component names correspond to `tolower(what)`

`signature(x = "awssegment")`

  Returns a list with components containing the requested statistics. Component names correspond to `tolower(what)`

`signature(x = "ICIsmooth")`

  Returns a list with components containing the requested statistics. Component names correspond to `tolower(what)`.

`signature(x = "kernsm")`

  Returns a list with components containing the requested statistics. Component names correspond to `tolower(what)`.
