This course about R is perfect, it gives you the tools and knowledge you need in order to do data analysis. I'm going to recommend this course to my peers, thank you coursera.

You need to have some programming experience to take this course. But overall shows you a good deal of R language. I really would which to see more about charts in the future.

The assignments actually go beyond what has been taught every week but on the other hand, they were big chanllenges which really did benefit to improving my programming skill.

I found the material presented in this course to be extremely informative and useful. I would highly recommend this course to anyone that wants to become more familiar with R.

It is indeed very instructional! I really learned a lot with each assignment, some have been easy and some have been hard to work, but in the end everything is well explained.

I learned a great deal in this course about manipulating data in R. It was challenging enough with a programming background, but not too time-consuming with my busy schedule.

I found this course challenging, cause I had no programming experience. But I'm being grateful for the community, which helped me in each step to overhelm some tricky issues.

Great introduction to R. The assignments are tough, but stick with it and the result is fulfilling!

I now feel more confident with R and will seek to use it more in my career

Exceptional program, but I cannot overemphasis how important it is to read the 'pinned' forum posts before embarking on the programming assignments. It will save you hours!

Challenging and educational. I learned way more things that I expected. I would just like to mention that there is a difference in difficulty between videos and assignments.

This course is so great! I learnt a lot of useful knowledge about R. Besides, I experienced a meaningful study progress on Coursera. Therefore, I really appreciate the JHU!

This class is packed with clear, concise and useful information. The level of difficulty was perfect for me. I learned through well designed exercises the fundamentals of R

The programming assignments in the end were very much challenging. I was not able to focus on any other activity when i got stuck at a problem. Very happy with the course.

Great course! I'd say that the assignments are very challenge for someone who never have programming experience before. but overall it's a great course and I learnt a lot.

Clear and understandable.

Would have appreciated a bit more of depth in the functioning and programming behind some of the exercises to be given during the video sessions.

Is a very useful course although you need more hours to complete it.

Also you need practice a lot. Use swril to practice. It is high recommended. Thanks to the instructors

I loved the way that this course has been structured. In addition, the sheer number of users makes this course more enjoyable since you can get your queries solved easily.

I found this to be a good way to be introduced to R programming. This taste of what's to come solidified that data science and/or data analysis is the career path for me.

Best in all opinion to learn R in such a planned order ...Thank you Coursera and John Hopkins and definitely a big thanks to Prof. Roger D Peng, Jeff Leek and Brain Caffo

The data used for assignments are real world examples which makes the programming interesting. It would be helpful if the course provides sources for some other databases

The course is very good. I had learned it as a part of my graduate program and with this four weeks, I learned much more than what I knew and used in one year. Thank you

Nice introduction to R language.

Because one thing can done by several way, and after learning about different methods, in beginning it's becoming confusing what to use.

I really enjoy it although it is tough for a begginer specially the assigments but there is help in the internet and the forum so it is fun and good to learn thanks lot

It was a great experience, the best course ever and the best materials, even when I had no time I downloaded the course and studied it, coursera is the best place ever!

It was a wonderful experience. I have learnt and enjoyed the course throughout the duration. The assignments were also interesting and focused a lot on the fundamentals
