    Hi,

    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

    http://rapid-i.com/component/option,com_myblog/show,50-Processes-on-myExperiment.html/Itemid,172/

    Cheers,
    Ingo
