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.
Really interesting course. The interactive coding sessions with swirl are especially useful. Would be great, if you provided sample solutions for the programming assignments, in particular for week 4.

The course is misleading - the difficulty ramps up too quickly, with the result that those who do not have a programming background will not be able to keep up. It should be toned down and reworked, or split into two courses. Cramming everything into 4 weeks makes everything too difficult.

The teacher goes very fast with the concepts without really spending much time on each of them. It will be great if instead of covering all things in short amount of time, the teacher could write R code using each type of function in console so that students know exactly what to expect.
By Albert W•
The gap between the lecture materials and programming assignment is enormous. So much of lecture seem to be on the history and theoretical of R programming that it completely fails to cover the material needed to actually completed the programming assignments. Incredibly disappointing!

Only take this course if you're already familiar with the basics of R programming, otherwise don't bother. The instructor is no help and you'll have to search the internet to complete the required assignments. Don't know about skills but this course sure gave me a lot of stress.
By Lefteris L•
The lecture material was very poor in terms of content and barely scratched the surface of the topic. I don't consider that passing this course you will learn anything but the very basics of R programming. In that respect you are better off reading a book on R.
By Jasen N•
For an introductory course with no prerequisites, the assignments should cover material that has been introduced in lectures. Non-introductory and advanced courses in R can require students to look outside of lectures for completing relatively complex problems.
By Sydney R•
BEWARE. If you are someone who is new to more advanced math or to any sort of coding, this course will be very confusing, totally unpractical, and you'll walk away not feeling like you've really learned how to use R in a real way.
I was incredibly disappointed.
By Huw M•
Wow. I cannot believe how difficult that last week was. No explanation for how to go about it just a learn it in your own time. As soon as the $49 USD is taken out of my account the difficulty is raised considerably. Cannot believe I paid for this subject.
By Adam G•
This course is poorly structured and the lessons don't prepare you in any way to complete the assignments. Don't waste your money taking this course and find something else. Johns Hopkins University should be embarrassed to have their name on this course.
By ADITHYA P•
The lectures are good for basic understanding, but there are no sample programs in order to understand their real world application. And the assignments are not at all for beginners. There is a huge gap between the content and the assignments.

To be honest, this is the most terrible course that I have ever had on Coursera. The courses are not well organized, and the assignment has little to do with the videos, which means students have to learn by themselves to finish the assignment
By James B•
Poorly organized and managed. Each week of this course should have been broken down into individual 4 week courses. I have 20 years software development experience, and I can tell you this is too much information to cram into a single class.
The new platform Sucks!!!
The people who just want to learn for free and not purchase a certificate are barred from attempting the quizzes unlike the old platform. Not being able to take the quizzes completely ruins the learning experience.
By Bich T T•
You don't have to go through the videos which I found painful because of the instructor's voice. The textbook includes everything in the videos. However, there was no application for the videos and textbook in the quizzes and assignments.
By Mohan U•
I really wanted to learn R in my current Mac iOS environment, in a Linux/Unix environment. I only see here the course offered in Windows environment in archaic MS-DOS environment? I am not interested in that. Hence I unenrolled.
By Marcos V•
The course is poorly designed with link between assignment and course material being so wide. This sometimes creates frustration of quitting the course. This made me think whether this course was designed to learn R or make money.
By Baurjan S•
Somewhere during the second week there is a gap in coding that I could not overcome and this ruined the whole interest in pursuing the course because in order to overcome it I had to cheat. I don't feel like I am learning anymore.
By Lancer B•
This class is a travesty in learning R. The lessons are misguided and do not prepare you for the overwhelmingly difficult homework assignments needed to complete the course. I would not recommend this to anyone trying to learn R.
The topic which was discussed by the professor can't match with the assignments and quiz.
I think the video of teaching should add more elements of practice, so that it would fit people with no basic knowledge of programming more.
By Rani B•
There is a significant gap between the lectures and assignments. For someone with very limited programming background, this posed a great hindrance to my ability to use the resources provided to be successful on the assignments.
By Stephane G•
Possibly the least well structured class ever. Also, not made for people to actually learn how to program in R. It is sad that I paid for this, and ended up going to another resource to learn... and it was much much easier.
By John S•
Not a class for the beginning programmer. The lectures do not line up with the assignments, and if you don't have programming experience, you could easily spend 10-20 hours/week figuring out how to finish the assignments.
The ask in the fist assignment was not formulated correctly. Felt the class needed more hands on learning. Although the lectures were clear and concise, going back to them really didn't help me with the assignments.
By Jose R•
I think there is a total mis-match between the lesson material and the assignments. The amount of hours one needs to search the internet to augment the training. The recommended text doesn't even come close in
By Alexander J•
I don't feel like I really learned R from this course. I felt like they just made me aware of some features. Also, there was vast difference between the course lectures, swirl and actual assignments.
