DISCRETE DATA ANALYSIS WITH R : VISUALIZATION AND MODELING TECHNIQUES FOR CATEGORICAL AND COUNT DATA by Michael Friendly, David Meyer, 9781498725835
"This is an excellent book, nearly encyclopedic in its coverage. I personally find it very useful and expect that many other readers will as well. The book can certainly serve as a reference. It could also serve as a supplementary text in a course on categorical data analysis that uses R for computation or―because so much statistical detail is provided―even as the main text for a course on the topic that emphasizes graphical methods."
―John Fox, McMaster University
"For many years, Prof. Friendly has been the most effective promoter in Statistics of graphical methods for categorical data. We owe thanks to Friendly and Meyer for promoting graphical methods and showing how easy it is to implement them in R. This impressive book is a very worthy addition to the library of anyone who spends much time analyzing categorical data." (Alan Agresti, Biometrics)
