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.
