R: Residual and Fit Spread Plots

B_10_rfs {lattice} | R Documentation

## Residual and Fit Spread Plots

### Description

Plots fitted values and residuals (via qqmath) on a common scale for any object that has methods for fitted values and residuals.

### Usage

    rfs(model, layout=c(2, 1), xlab="f-value", ylab=NULL,
        distribution = qunif,
        panel, prepanel, strip, ...)

### Arguments

`model` | a fitted model object with methods `fitted.values` and `residuals`. Can be the value returned by `oneway`
`layout` | default layout is c(2,1)
`xlab` | defaults to `"f.value"`
`distribution` | the distribution function to be used for `qqmath`
`ylab, panel, prepanel, strip` | See `xyplot`
`...` | other arguments, passed on to `qqmath`.

### Value

An object of class `"trellis"`. The `update` method can be used to update components of the object and the `print` method (usually called by default) will plot it on an appropriate plotting device.
