Very challenging, but good course. I've been programming in R for over a year, but there were still some things for me to pick up in this class. Assignments were a challenge, but satisfying to tackle.
"R Programming" forces you to dive in deep.\n\nThese skills serve as a strong basis for the rest of the data science specialization.\n\nMaterial is in depth, but presented clearly. Highly recommended!

I found the video explanations sometimes not enough precise especially regarding the lexical and dynamic scope, however the assignment and the exercises have been for me very useful to gain all competences I was looking for. I really appreciated the combination of exercises and assignments, even if not really easy, but really useful to learn R programming.

I think it would be better if everything you ask in the assignment tasks were alredy cover by the course. i found myself in the need to search and investigate somewhere else (wich is kind of good sometimes) to now how to solve the problem. My issue is that the difficulty lvl for the tasks were too high in comparation with the things learned in the course

The course is awesome and great to get you hands on with R programming. The course focuses on various aspects of R programming and what I think most important is it teaches you to write functions is R which is the key to accomplish significant projects using R. Thanks to Dr Roger D. Peng, Dr Jeff Leek, & Dr Brian Caffo, for creating such useful course. :)

My name is Jose Antonio. I am looking for a new Data Scientist career ( https://www.linkedin.com/in/joseantonio11)
I did this course to get new knowledge about Data Science and better understand the technology and your practical applications.
The course was excellent and the classes well taught by the Teachers.
Congratulations to Coursera team and Teachers

R isn't easy to get familiar with ... spoken by a C++, Java, Python engineer. This course was effective at introducing the essentials of R for inputing, manipulating, presenting, along with a basic IDE and debugging/profiling toolset. I am still wondering when python/R is the better platform ... but presently believe I'm far better off knowing both.

Very good. Even though that it is not completely required to know statistics for this course, I would suggest putting in the requirements something like "basic statistics". For example, I don't need to know about the Poisson distribution in order to apply its function, but at least I might want to know why is it useful to apply those kind of functions.

It took me quite long time to complete this course because of challenging assignment and many practical application. This course made sure that I not only learn the theoretical part but also I practice and become confident in what I have learnt. Personally, it was very fruitful course as after learning this I could really use it in my day to day work.
por Nino P•
Great course for anyone who wants to learn R! I had no prior experience in R and it helped me to start and learn basics. After this specialization I really feel confortable working in R. I would not recommend this course to someone with good knowledge in R since you will be bored, but for every begginer it's a must do. This specialization is amazing!
por Benjamin A T•
This course is a comprehensive introduction to R, ranging from the very basics of the language to more abstract concepts like scoping and object-orientation. For the beginners, the quizzes and the hands-on exercises are not straightforward, which is better to force the student to dive into the programming language. I strongly recommend this course!
por Victor A d S P•
It is a great course. I have already had experience dealing with R, so it helped me a lot to fix somethings that I had problem with. However, I would assume that in order to take this course, you would have to have some previously owned background in Programming. Even though, it is a great course, I just loved it. Take it, if you enjoy a challenge.
por Praveen K P•
I really want to take moment to appreciate the careful designing of course material. Start from basic and touched every major point of programming. At least we can take this knowledge ahead and use this in more real world scenario. This has given me enough encouragement to stay connected for future guidance. Kudos to Course designers and Coursera.

The flow of the course is really justified. Swirl is really the best part of the course. The course should have more lessons on making functions as making function are really difficult and need to look for lots of sources to form a correct one. I really pay tribute to the makers of this complete course. It is really going to help me in my PhD
por Ulrike H•
This course is well structured and the explanations are understandable. I liked best the practice R sessions using the swirl package. Cool thing. I found it a pity, that a few acompanying lecture slides are missing for download. It would be nice if they were available, because they are helpful for programming assignment 3 as cheat sheets.
por Adam G•
Learned a ton in this course! Kind of felt like Excel 101 for R, began to understand most of the basic functions and their use cases.
It was much much harder and work intensive than part 1, took 5-10 hrs/wk. Can't just knock everything out in 1 day, takes consistent workflow.
Recommended if you want to learn, felt challenging but rewarding.
por Chris C•
Was tough enough to give me the feel of solving real problems. Would have appreciated a little more explanation of the return types of the looping functions, all time was spent on the parameters and no time on what the data structure returned is. Online documentation is also weak on this point so some instruction would have been helpful.
por Vinayak N•
Pedagogy is amazing, instructors comprehensively explain different concepts with ample scope for practice. swirl() package helped me gain some essential skills in the language as well. I would thank Coursera and Johns Hopkins university for putting together such courses in order for us to learn from such great experienced professors.
por Gawaine O•
This R programming course was well done. Only thing I would suggest is more outside textbooks or websites that offer exercises. For example, a link to another website that does in-depth about manipulating data frames. That would greatly help out with the programming assignments that can sometimes seem different from lecture material.
por Ivan M M•
A fantastic experience for beginners in R, but also challenging if you have little experience in programming as it was my case, I will recommend it to anyone who wants to learn R and are willing to invest time and effort, probably would not recommend it if you just want to take a glimpse of how R works from just an user level
por Nikolay B•
Thank you, providers! - Well done. Got basics of R, and can use on my job. Liked swirl(). R seems the language well thought in its design. It is a good course. I have personally mentioned some rushy behavior closer toward 3/4 of the course. Last chapters are banal for someone experienced in programming. Overall, nice intro.
por Austin C•
I am absolutely in love with Coursera and their course offerings. The information is presented in short, meaningful bursts that allow for proper processing and understanding. I've taken online courses from various other companies, and very few of them come close to matching the elegant design and presentation of Coursera.
por Margaret O•
It was an awesome experience having to totally dedicate time to really study and learn a whole lot with R. The structure of the course for me prompted me to do further research aside from the materials provided. That enabled me to learn even more than what is contained in the materials and videos. It was indeed awesome.
por RENJITH M•
Even though the lectures are shot and to the point, the assignment helps you to learn many things by yourself. If you try to complete the course within the timeline, an automatic urge to find the solution will come within you. This is required in distance mode/online education otherwise people don't finish the course.
por Ron E•
Excellent introduction! I have been using R on and off for the last 8 years, and have also used it while doing a Masters degree, but was never given a thorough and proper introduction of the basics. This should be an absolute must for anyone using R as an analytics tool be it as an academic or an industry practitioner.
por Daniel F•
This course is perfect for learning to program in R. The only drawback is that for people who know nothing about programming some exercises can be quite difficult, in particular the functions you need to do for the assignments in weeks 2 and 4 can become an almost impossible task if you have no idea about programming.
por Naveen S•
This is exceptionally nice program, it really give me a great sense of R and some absolutely fascinating skill to work with data. Lecture are really well drafted and pretty comfortable in understanding, mentor are responsive and replied as quickest as possible. Looking forward to gain the expertise in R programming.
