additional arguments are passed to <code>xyplot</code>.

Overlaid screeplot for the models in a &#8220;covfm&#8221; object.

The fit.models function and its associated methods (coefficients, print,
summary, plot, etc.) were originally provided in the robust package to compare robustly
and classically fitted model objects. See chapters 2, 3, and 5 in Insightful (2002)
'Robust Library User's Guide' <http://robust.r-forge.r-project.org/Robust.pdf>). The aim
of the fit.models package is to separate this fitted model object comparison functionality
from the robust package and to extend it to support fitting methods (e.g., classical,
robust, Bayesian, regularized, etc.) more generally.
