What I really like is that the author never tries to "sell" R to the reader. This is rather refreshing, because I always get turned off when books beginning with a sales pitch for something I already clearly south
First things first, this volume really lives up to its name! It's a thorough introduction to programming in R, aimed at software developers. This is non the volume for you if yous desire to larn about the statistics side of R or how to make prettier plots, there are plenty of books virtually that anyhow.What I actually similar is that the author never tries to "sell" R to the reader. This is rather refreshing, because I e'er get turned off when books offset with a sales pitch for something I already clearly showed involvement in by purchasing the book. R is a rather specialized language and chances are that you know why you lot want to solve a given problem in it, and if you don't, this might not yet be the book you should exist reading anyway. The showtime few capacity cover the language'due south basic data structures like vectors, matrices, arrays, lists and tables, before affiliate 7 introduces various catamenia control structures. What follows is a chapter on doing math and simulations in R, which is non overly long simply gives some good examples of what the language is useful for. The next affiliate is very interesting, it deals with R's object oriented features and describes the differences between S3 and S4 classes too equally their respective up and down sides. After this the author covers input/output, dealing with strings and R'southward graphing capabilities. He never gets lost in detail, but provides you with enough info to be able to explore these areas on your own. What really makes the book special though are the terminal few chapters, where Matloff covers debugging (a topic he also wrote an entire book about), performance tradeoffs, interfacing R with other programming languages (using functions written in C/C++ from R, as well as using R in Python) and various approaches to parallelizing R. While none of this may sound super exciting at start — apart from parallelism maybe — these are important issues in the daily lives of software developers and way besides many books just gloss over them.
Now for some criticism: personally I don't observe the author's mode very engaging, it'southward rather dry out and boring at times. Since it'due south clear that Matloff is an absolute say-so on the topic of R this doesn't manner as well heavily, but still deserves a mention. Too for my personal taste there are slightly also many forward references in the text, although that'south hard to avert if yous want to properly cover a language. I also establish it rather odd that at one indicate the author mentions that explicit return statements aren't exactly idiomatic in R, only that he volition keep using them for the benefit of readers unaccustomed to the linguistic communication. Given that this was a few chapters in, it would have been a perfect spot to switch to the more than idiomatic manner from then on, only maybe that'southward just me being nitpicky. I also noticed several little typos and misspellings, something I'1000 not actually used to from No Starch Press.
All in all this is a very solid book, which y'all definitely should pick up if you want to learn programming in R!

Exist aware that for some of the bug at that place are better solutions around already, nearly importantly:
* for the connection with python at that place is at present the reticulate package
* for parallel calculating much changed
* through Hadley'south dplyr and strin In 2020 this title is slightly outdated, but still a must read if you want to up your R game. If y'all think about buying one book at a good price, then become this 1 and complement it with the free online version of Hadley Wickham's Advanced R (now in version 2!).

Not only does information technology go through all of the basics of the language, information technology besides recommends some modern packages which make everything easier (plyr for case) - with copious examples and "advanced examples".
I only have two problems with the book:
1) Sometimes, the advanced examples are too clever for their own good. They're meant to showroom the advanced usage of the main focus of the current chapter, but
If you're looking for a book to read equally a full-on introduction to R (and advanced R), take this book.Non simply does information technology go through all of the basics of the language, information technology also recommends some modern packages which make everything easier (plyr for example) - with copious examples and "avant-garde examples".
I only take two problems with the volume:
i) Sometimes, the advanced examples are besides clever for their own good. They're meant to exhibit the advanced usage of the main focus of the electric current affiliate, but they and so ofttimes do something exceedingly clever that you lot first have to become through the lawmaking step by step with a piece of paper to understand the basic algorithm. Simply then can you go on and sympathize the usage of the data-structure or control-construction in question.
2) It can't make up one's mind whether it'southward an introduction or a reference. The book is written and structured similar an introduction, but it seems to exist on a quest to introduce the majority of standard functions that R has (and they are legion). I'm pretty sure I already forgot about eighty% of the introduced functions.
Similar almost programming books, this one focuses too much on syntax and data structures, and not enough on problems you tin can solve with the linguistic communication. But other than that it'south well-written. If you want to practice annihilation having to do with statistics, R is a great linguistic communication, and this book volition teach you how to use it.

The initial chapters talk almost the foundation concepts like vectors and matrices. The examples are simple enough to beginning with, while the author leaves some room for cocky-experimentation. The latter chapters depict the advanced capabilities like graphics, debugging and operation tuning.

This book IMHO is an first-class starting point for learning R. I'thousand finding information technology really useful for beginners like me to learn this new programming language. The volume is comprehensive and well-illustrated.The initial chapters talk about the foundation concepts like vectors and matrices. The examples are simple enough to kickoff with, while the writer leaves some room for self-experimentation. The latter capacity depict the avant-garde capabilities like graphics, debugging and functioning tuning.
Needless to say, I'll require a lot of practise to become comfortable thinking in R terms, merely this book definitely laid the stepping rock for me.

This volume is primarily a tutorial. The index is of mediocre comprehensiveness so I cannot recommend it as a reference book.

In brusque, overall, it is a worthy book. It touches most of the aspects when programming in a modern, Large Data capable language R. And not quite at the same time. To elaborate more, permit me state correct away this is non Norman's fault. Its R's. Carry on. Starting from the starting time pages till the last you will be made very well enlightened that R is slow. Well, I read somewhere, an opportunity for publishing a review online is a tribune for a fool. I will practice my right whether yous agree or not. I don't.
In brusk, overall, information technology is a worthy book. It touches nigh of the aspects when programming in a modernistic, Big Data capable language R. And not quite at the same time. To elaborate more, allow me state right away this is non Norman's fault. Its R's. Carry on. Starting from the first pages till the last you will exist made very well aware that R is ho-hum. I was even annoyed by the constant reminders, however I did not deduct the star for that. I must tell you even before buying this book I did some research and found out that Julia (julialang.org) is a fashion improve designed statistics programming language, alas it stuck at the RC 0.3 level for likewise long and patently at that place is no skillful literature to learn information technology (yet, as I know of a new book in cooking). Did I say this book was highly recommend? Yet, it seems that the R buzz has penetrated all the Big Data remote corners (err, I hateful cubicles). R remains valuable, coming out the academia to mere mortals.
So, an R programmer will benefit from knowing C, GPU, sockets and threads, will spend time debugging in an editor or beat out and have on code operation optimizations. Not for a timid soul.
The book is not going to make your a totally ready to get and plan, but it will set up a solid background for the further R exploration. This book needs to exist read among the first. I institute the comprehension is too shallow to mark it five stars.
One communication to the author and publisher, the book needs a second edition, refresh. ...more
Having thus driven this book to the ground, I have to say that professor Matloff seems very knowledgeable in R internals, C and C++ programming and diverse kinds of parallel and high-performance computation - all subjects treated in the final tertiary of the volume. I weren't looking for those in a book called "The Art of R Programming", but they were somewhat interesting. If these subjects interest you, you might find some good information in this book (but beware the beginning ii thirds). If you are looking for a good book to learn R, choice upwardly something else. By no ways should you read this as your first book on R - I wouldn't be learning it now if this was my beginning volume on information technology, as it gives absolutely no justification why it's worth the time.

Overall, I found the volume very useful. I previously had fairly extensive knowledge of general R syntax and functions, only this text was good for getting a slightly more formal and in depth run through of various R quirks. Definitely ane of the all-time books on R.

Later on getting skilful at the basics of R, i can become for other books for specific requirements (like whether you desire to focus on graphics/plots or on statistical modelling).
