Vietnam

A survey of student opinion on the Vietnam War was taken at the University
of North Carolina at Chapel Hill in May 1967 and published in the student
newspaper. Students were asked to fill in ballot papers stating which policy
out of A,B,C or D they supported. Responses were cross-classified by
gender/year.

datasets

Provides additional data sets, methods and documentation to complement the 'vcd' package for Visualizing Categorical Data
and the 'gnm' package for Generalized Nonlinear Models.
In particular, 'vcdExtra' extends mosaic, assoc and sieve plots from 'vcd' to handle 'glm()' and 'gnm()' models and
adds a 3D version in 'mosaic3d'.  Additionally, methods are provided for comparing and visualizing lists of
'glm' and 'loglm' objects. This package is now a support package for the book, "Discrete Data Analysis with R" by
Michael Friendly and David Meyer.
