Really enjoyed this course and found it both challenging and informative. After having taken it, another user's advice seems appropriate: Watch the lectures, but reserve your time for the assignments. They can be tough, but that's really where you learn.

Great course! It is the second course of the Data Science Specialisation I have finished so far, and I really enjoy how it goes. However, in my option, some assignments lack clear instructions, what still does not prevent students to complete the course.

Great introduction to R programming. Much more rigorous than other primer courses. The quizzes and project really make you think, and you feel like you accomplished something at the end. I would highly recommend this course to anyone wanting to learn R.

The course structure is very well crafted. The pace and learning curve goes smoothly although starting third week, you would need external resources for help. You do get to learn a lot about R as a computational language with great hands-on experience.

Excellent and challenging introduction to programming in R. Plenty of materials to help you along the way and the course is delivered at a reasonable pace in a friendly and clear manner. Would highly recommend if you want to get into programming in R.

Excellent course, it is my first time in R programming, and with this swirl package I learned a lot, then complete the training with the thinking to complete the assignments that are challenging and are excellent choices since real live is not easy!

Great course as an introduction to R programming. The course provides a base on which I could build upon. I enjoyed the programming assignments which exercised my ability to troubleshoot problems and search for answers on google and stack overflow.

I find the course very interactive. I want to say thank you to the team members of John Hopkins University for their hard work. I always feel pleasure in learning new things and Coursera has given me this opportunity by creating this MOOC platform.

Best course I have completed on R. As a new bee in R language, assignments was really a tough challenge for me. Now I have gained basic understanding of R language and I hope to do an advance course on R as well in future from Coursera. Thank You!

I didn't know anything about R programming before enrolling in this course. The interactive teaching style (swirl exercises) and the relevant assignments contributed so much to my learning. It was a good decision to invest my time on this course.

Very well-taught and well-structured course, with great instruction by Dr. Peng. The programming assignments really helped with the practical aspect of R. Overall, this course is an excellent foundation for the programming aspect of data science!

Such a nice introduction to R Programming! I urge you to take this course if you need essential guides to enhance your coding skills and programmer's mind. Assignments are challenging but rewarding enough to bring you feelings of accomplishments.

The last exercise was excellent (Week 4). Each question exposed the chinks in our code. This challenged the learner to refine the code to plug all holes. However, what I am not sure is how effective is my coide against failures and against speed.

the assignments might be a little bit difficult for beginners to start with but that is what which will trigger a hacker in you and in turn will compel you find the answers and explore new and innovative ways of solving highly convoluted problems

You can learn basic functions of R and do practical assignments on your own. However, the assignments are a little bit challenging, and students need to take some time to figure it out, especially for people who are not familiar with programming.

Undoubtedly the best course on Coursera! This course is great fun, challenging, and loads of learning! I highly recommend this course to all the learners! Thanks to the instructors and the Johns Hopkins University for such a magneficient course!

Very useful course for beginners and intermediate users of R. It gives some very important insights about the infinite potential of this programming language. Definitely recommended for people who use R for professional and/or academic reasons.

Great introductory course in R. Swirl is a very good introductory method for learning R by 'doing it'. The set of exercises were great (allow us to explore R in a more deep level), with very detailed and easy to follow instructions. Recommend!

Excellent introduction to R Programming...whether you are taking it stand-alone, as part of the data scientist specialization or want to ease into the machine learning side of things . The swirl() exercises are a helpful add. Kudos to the team.

This course provides a great overiew to introductory R programming. Since taking the course, I have successfully used the precepts learned here for a number of analysis projects. Coupled with ggplot2 graphics, the results became self-evident.

A good course to start with the fundamental and there is no better way than to learn hands-on which the assignments do help with. Would recommend for beginners as the videos cover a lot of topics. Improvements can be made but i like the course

Great course. But please consider including a reading version of the video lecture, (not the same as the transcript) just like in the previous course (The Data Scientist Tool Box). I found those reading versions of the lectures really useful!

Great course, I loved the SWIRL module. It was awesome. The videos were great and the examples really well though. The instructor has a great voice, he should consider a side job as a narrator, he could do it great.

Honestly, I just loved it.

I like this course so much.just because when I was doing this course I have learnt so many thing that will help me in future and thankyou so much sorry for giving me this opportunity.i will surely do more course and learn new thing from you.

This course will provide you with fundamental knowledge about R. It does not only teach you how to do things, but why to do them and it also covers how R works behind the scenes. This is valuable knowledge for anyone wanting to work with it.
