The course was quite useful. The assignments were challenging. The fee, however, could be charged for individual courses rather than for the entire specialization as it would give more freedom to the learners.

Very good introduction to R Programming. It would be especially good if at the end of the course there were some model answers, though I appreciate the problem of answers transgressing into the public domain!

Good course to start working with data analysis with R.

In my opinion, Peer assignments doe not work properly for this type of course.

I got a Zero from a peer who definitely hadn't any idea what she was doing.

An order of magnitude more difficult than the intro course. Unexpectedly tricky at times ( esp. if you're primarily versed in programming & not stats ) but more all the more worth it for the difficulty spike.

Great content,but for a beginner like me,I think the course should have more and more code assignment starting from short and easy to the final assessment.On solving the coding assessment,I felt intimidated.

He aprendido bastante sobre un tema que era desconocido para mi, no ha sido fácil precisamente por lo anterior; sin embargo, las tareas de Programación no son tan claras en las especificaciones que se dan.

I completed this course with blood and sweat. Programming Assignments will make you doubt yourself. Basic knowledge of programming is recommended. Although course is heavy, its quite informational as well.

O curso é interessante, principalmente os exercícios. Porém, o que é dado no curso é muito simples perto da dificuldade das provas. É necessário MUITO estudo extra para que seja possível terminar o curso.

A decent course overall with a VERY steep learning curve (even more so for those who don't touch R on a regular and intense basis), but if you are looking to expand your R skills, this course is for you.

Class is very interesting and eye-opening. I have to agree that it was very difficult for me to get all the working programming done correctly. I had a hard and frustrating time. I enjoyed it, thought.

Great course, very well structured. Just one thing: for an absolute newbie in programming, it is extremely challenging. Some more guidance, practical exercises, step-by-step explanation would be great.

Get ready to use stack overflow and google a lot. Videos are more technical but give you a good oversight of what R functions r like. Assignments were sufficiently challenging as a beginner programmer.

Found lectures to be only somewhat helpful. More engaging production as opposed to just voice over ppt would be much better. Learning tools could also be improved to take advantage of technology.

Great course really helpful. But only 4 stars, because I wasn't really prepared for the 2nd Assignment (Lexical Scoping), based on the lectures, and the cache assignment operator wasn't well explained.

It was a great course with an excellent teacher (Prof.Peng) who teaches all of the contents with extra details. However, I think it would have been better to bring more examples during teaching time.

For a newbie in programming in general, this course covers a big picture in that dimension. Even though the difficulty spikes are pretty notable in the assignments, the course is fun and challenging.

Although it was a little difficult for me with no computer programming background, I found this course to be a great introduction to R programming. Lots of important concepts and basics are covered.

Nice course but it would be better if more links to this course and exercises were added for students to be able to have more practices not only with swirl ( ) but also with trustable third parties.

Very good programming course. I just would have liked the demands of the tasks to be in accordance with what they give in practice or materials. The tasks seemed difficult to complete, without help.

I would have preferred the 'robot voice' concept from the toolbox course, since it could be updated to more recent R upgrades, but the assignments really made me think and that was my favorite part.

The course was a wonderful introduction to R, though I felt the programming projects were lacking a bit in terms of direction. Definitely go through the swirl exercises to help reinforce everything!

This course is a good starting point for learning the bits and pieces of R. It shows you how to work with data in a fairly easy manner.

The course is well explained and the exercises are challenging.

Quite good if you can cope with the pace. Absolute beginners may struggle. But exercises were challenging enough to make you learn and that's the best part of the course including Swirl Exercises.

This course was almost excellent. The tutorials were amazing. I am just going to complain about Assignment 2; inverted matrices weren't a pre-requisite so it was hard to understand that assignment

Helpful in learning the basics and then some. However, the course assumes you know certain things about the R language and a lot of catching up had to be done (learning from outside sources etc.).
