Dear Marco:

Alan Agresti in "Categorical Data Analysis," p. 291-3 describes the use of
correspondence analysis and provides an example.

Laura Thompson in "Splus Manual to Accompany Agresti's Categorical Data
Analysis" implements Agresti's example on p. 45-6. Some slight modifications
will render the example in R.  Her paper can be found on


This might be of benefit to your work.

Best wishes,
