Great course! Really useful. It can get difficult at some points, I found that the course doesn't prepare you so well for the assignments if you don't have any background knowledge in programming. However, it is a great course to take.

Overall a very good class. It provides a good introduction to the R programming language with assignments that prompt you to use these skills. However to become proficient more practice is required, just like any programming language.

It brought to me not only the technical ability to work with R but also reminded me of the conceptual gaps I have to fulfill in order to be a better data scientist, more specifically regarding the depth of the knowledge of Statistics.

Very useful course for getting started in R Programming. I would advise to take this course for everyone, who is interested in working with data. I had a pleasure to complete the tasks and to get knowledge about new things! Thank you!

Although I gave a good score in my evaluation, I think that the course should have more practical explanations... The last two assignments and tons of students in the forum may confirm what I'm saying.

I am grateful for this course!

It is a great course for learning deep foundations about R programming. The programming assignment were a good challenge for learning a lot of advanced things. Thanks coursera and Johns Hopkins University for offering this course!

I've taken a bunch of online programming courses. This one is the best. I loved the swirl package exercises. They make R very easy to learn. The tips in the discussion forums are very helpful for getting assignments completed.

The course content is well thought out, covering from very basic to more advanced topics at a steady pace. The assignments are challenging but is doable with some personal research and persistence. Enjoyed the experience overall!

Assignments are good however there needs to me more practice in swirl to cover various functions and libraries, also the question set can include more questions with some dynamic set that changes a bit more in every next attempt.

Great way to learn the fundamental building blocks of R. it is east to get stuff done by just copy pasting snippets of code from StackOverlfow, however this course gives you a good primer on R data types, variables and functions.

Really interesting and challenging course.This course has help me understand R much deeper. It also show me how versatile and powerful of R that capable to help us to solve our problem with a simple and effective way of coding.

This a very good introductory course to r. I had to prior knowledge to programming but the instructor was explaining all the concepts nicely. I recommend the course for everyone with a background in Mathematics and Statistics.

A great course to advance programming skills in R. Assignments are sometimes challenging, but that´s also what makes it interesting and even more fun if you mastered the challenges and reached your goal. I highly recommend it!

Great Course that introduces to R Programming. The level is high but not too difficult.

It introduces to different Programming methods (new to me that come from Functional/Object-Oriented Programming Languages and environments)

Its really well concieved. I didn't have to have past experience in statistics to learn R, yet since I do have some background, it was fun to mess around with it.

I learned enough to get me started with R. Thank you very much.

R programming is a great tool aside with python and shell I have learned from the Genomics data science specialization. And now is time to think about building my expertise for biostrings and bioconductor to grow my toolbox.

I am so glad that I took this course, I have learned very useful R coding skills. Some assignments were challenging, but this has made me learn better. Big thanks to the instructors and for the helpful community and mentors.

Really nice introduction to a different programing language. To me that have a background in frontend and web backend language, it was a little different and nice introduction to mathematical/statistical programing language.

I am really very happy for completing the course. The difficulty level of the assignments can be scary at first glance, but with the help of the mentors in the forum and their complementary lectures, they become achievable.

Very good introduction to R, and its use of data structures, indexing, logical arguments, lexical scoping etc. The problems at the end really ensure you come away from this course with sufficient knowledge. Would recommend.

This is a really useful course on the basics of R programming. The instruction is clear and friendly to novice programmer. Certainly, this course only opens the door for you, more useful stuff will be learned from practice.

Excelente, seria bueno que en los foros de discusion o en un apartado llamado recursos, se tuviera un tutorial en donde se den algunos tips o ayudas al momento de escribir codigo para las tareas de programacion asignadas.

A great introduction, my only suggestion would be to add pdf notes to the 3rd and 4th weeks so the course could be totally self-contained. This is not a real issue, however, because the book is provided for free/donation.

its very good course and I seriously inspired the way it teaches me, first time I opened R programming and now I am little more comfortable, hope and wish I will continue my zeal toward data science, thanks for the course

Challenging, not really for beginners but amazing! You should be familiar with programming and statistics if you want to have full grasp of what's going on. I loved the programming assignments and swirl was very useful.
