CRAN Recipes: DPLYR, Stringr, Lubridate, and RegEx in R

The author states that the book is not intended for beginners nor for absolute R experts. He hits his mark on this goal. It is a very well written book with numerous examples. I am particularly interested in stringr and regex and this is a great resource for those subjects as I have read them thoroughly. The remainder of the book appears of equal quality, but truthfully I have not read them. I ordered the "real book", (not an electronic version) as I prefer that. Many books have such a terrible font and line spacing as to be very difficult to read. That is not the case with this book as it has a very comfortable font and line weight and also the line spacing is ideal. One more thing, although this is a computer book and you expect very little (or no) humor, this book does contain some humor (which is a good thing). I give this 5 book stars. I own about 12 "real R books" and this one is clearly the best, IMHO ... particularly for stringr and regex. RMW

I am neither happy nor sad. This book is a nice reference or maybe good for one or the other inspiration, but if we are talking about recipies, it is more fast food than multi course menu. There is no really sophisticated code and although it says DPLYR it is a mixture of base and dplyr. For instance on page 40:subset.survey <- survey[1:10,]That's not dplyr, correct code would be (among other solutions) something like: survey %>% head(10)For practical matters it may be irrelevant, but for a dylyr purist like me, those things hurt and the book is full with code like this.Concerning other topics the book may be innocent, but being published in April 2021 already means it is outdated.mutate_if, mutate_all and so on are already superseded.All in all, nice but neither fish nor foul. 3 stars.
