there is a process on myExperiment showing how you can do that. Just install the Community Extension (in the Help menu --> "Update RapidMiner...") and activate the myExperiment Browser. Search for the process:
"Cross tabulation via aggregation and pivoting"
and download it. It will show you how you can calculate a cross table (contingency table) with RapidMiner.
More information about the Community Extension can be found in our latest blog entry at
