Ce livre est parfait pour les gens qui connaissent déjà bien R et veulent aller plus loin.J'ai découvert des choses que je ne soupçonnais pas, j'ai particulièrement apprécié le chapitre sur les graphes, celui sur les séries temporelles, le clustering... en fait il s'agit de zooms très utiles pour qui veut aller plus loin dans l'utilisation de R pour le data mining.

I found "Mastering Data Analysis with R" useful & very readable. I especially liked the sections dealing with obtaining, filtering & manipulating data. Though some of this information can be found in various R package vignettes, much of it, including useful tips, is all in one place here. For example, I found the section on using functions from the R package "dplyr" useful for merging data sets. The reader of this book might do well to follow-up this volume with Hadley Wickham’s "Advanced R". I also enjoyed the treatment given to importing the corpus for text analysis. Python generally seems to be a bit easier to navigate for the pre-processing step when performing text analytics. This book made conducting the process in R much easier for me.
