Ce livre est consacré à un outil désormais incontournable pour l'analyse de données, l'élaboration de graphiques et le calcul statistique : le logiciel R. Après avoir introduit les principaux principles permettant une utilisation sereine de cet environnement informatique (organisation des données, importation et exportation, accès à la documentation, représentations graphiques, programmation, maintenance, and so on.), les auteurs de cet ouvrage détaillent l'ensemble des manipulations permettant la manipulation avec R d'un très grand nombre de méthodes et de notions statistiques : simulation de variables aléatoires, intervalles de confiance, assessments d'hypothèses, valeur-p, bootstrap, régression linéaire, ANOVA (y compris répétées), et d'autres useful source encore.
