  "Description": "Contains functions to simplify the use of data mining\nmethods (classification, regression, clustering, etc.), for\nstudents and beginners in R programming. Various R packages are\nused and wrappers are built around the main functions, to\nstandardize the use of data mining methods (input/output): it\nbrings a certain loss of flexibility, but also a gain of\nsimplicity. The package name came from the French \"Fouille de\nDonnées en Master 2 Informatique Décisionnelle\".",
