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.
