Converts a frequency table, given either as a table object or a data frame in frequency form to a data frame representing individual observations in the table.
For glm objects, the print and summary methods give too much information if all one wants to see is a brief summary of model goodness of fit, and there is no easy way to display a compact comparison of model goodness of fit for a collection of models fit to the same data. All loglm models have equivalent glm forms, but the print and summary methods give quite different results.

Formats a brief summary of model fit for a glm or loglm object, showing the likelihood ratio Chisq (df) value and or AIC. Useful for inclusion in a plot title or annotation.
Given two ordered factors in a square, n x n frequency table, Crossings creates an n-1 column matrix corresponding to different degrees of difficulty in crossing from one level to the next, as described by Goodman (1972).
These functions generate lists of terms to specify a loglinear model in a form compatible with loglin and also provide for conversion to an equivalent loglm specification or a shorthand character string representation.
The data function is used both to load data sets from packages, and give a display of the names and titles of data sets in one or more packages, however it does not return a result that can be easily used to get additional information about the nature of data sets in packages.
