R: Compaison QQ Plot

qqPlot.lmfm {fit.models} | R Documentation

## Compaison QQ Plot

### Description

Produces side-by-side QQ plots. An optional simulated confidence envelope can be included in each plot.

### Usage

    qqPlot.lmfm(x, fun, envelope = TRUE, half.normal = FALSE, n.samples = 250,
      level = 0.95, id.n = 3, qqline = TRUE, ...)

### Arguments

`x` | an lmfm object.
`fun` | a function to extract the appropriate quantity from `x`.
`envelope` | a logical value. If `TRUE` a `level` confidence envelope is simulated for each QQ plot.
`half.normal` | a logical value. If `TRUE` the plot is drawn using the absolute values.
`n.samples` | a positive integer value giving the number of samples to compute in the simulation of the confidence envelope.
`level` | a numeric value between 0 and 1 specifying the confidence level for the envelope.
`id.n` | a non-negative integer value specifying the number of extreme points to identify.
`qqline` | a logical value. If `TRUE`, a QQ line is included in the plot.
`...` | additional arguments are passed to `xyplot`.

### Value

the `trellis` object is invisibly returned.
