variablelist

For a data frame with factor variables V1, V2, V3, etc having levels n1,
 n2, n3, etc, lists the n1*n2*n3*... possible interaction levels and
 identifies which of the observations of the data frame belong in which
 of these interaction levels.

Identifies potential data outliers and their impact on estimates and
analyses. Tool for evaluation of study credibility. Uses the forward
search approach of Atkinson and Riani, "Robust Diagnostic Regression
Analysis", 2000,<ISBN: o-387-95017-6> to prepare descriptive statistics
of a dataset that is to be analyzed by functions lm {stats}, glm {stats},
nls {stats}, lme {nlme}, or coxph {survival}, or their equivalent in
another language. Includes graphics functions to display the
descriptive statistics.
