Brilliant course. Loved Week 4 for OOP. This was really new for me and would love to have been able to see its application in real world examples to better cement the concepts.

Very useful, I considered myself quite an advanced R user, but this class raised the level, especially with the R as OOB part. Good investment if you are not a beginner.

Much of this course is well-constructed, well-communicated and clear. Sections from weeks 1-3 were attuned to my programming skill level and the material was communicated generally so that those with experience in other languages could also follow along easily. I had no technical problems with submitting assignments or quizzes and I found the assignments with swirl to be effective in reinforcing the material from the readings. My biggest criticism of this course is about Week 4's content and its respective part in the final assignment. The content in Week 4 concerns Object-Oriented programming and this material was really hard to absorb. It seemed to come out of left field and the readings did not feel as clear as they were in other sections. The readings essentially say "Here is what object-oriented programming allows you to do [create/manipulate classes and objects]" but then goes back on itself by recommending that you do not use object-oriented programming to create custom classes or data structures because the R community already knows what data structures they like. Personally, I had a lot of trouble understanding this content because it was so briefly explained. This did not help me by the time I had to complete the object-oriented programming portion of the final assignment. It is very clear from the class forums that other students have found that section of the assignment particularly difficult for years. Overall, this course was excellent in teaching functional programming principles and application, but the object-oriented section slightly spoiled my experience of the course.

It took me about a year to complete this course, but i had to stop to work on my honors thesis. This course was a good refresher to the nature of programming for me, as i hadn't done much for about five years (C programming). It has given me the confidence and tools to think about developing software for use in my future career (bioinformatics).

The lessons in this course were fantastic. The one thing that bothered me was the peer review system for assignments. You end up having to wait weeks just to finish the course, even after you're done everything. Other classes use automatic or paid manual graders, which give instant feedback. I think a similar system could work here.

The class does not cover all material needed for the final assignment in depth enough. I had to do extensive research outside of the class materials to be able to complete the assignment. I learned a lot, but I shouldn't have to do too much outside work to complete assignments for a class I paid for.

I think the course introduced some useful packages like purrr and concepts like map/reduce, but I think the explanation into the different OO systems could be improved. I struggled a lot with the final assignment and really depended on external sources of information to complete it.

Great acceleration of the specialization compared to the first course. It covers modern approaches (as map-reduce-filter implementation in purrr), nicely explains debugging, benchmarking, OOP etc. I would recommend this as a kick starter for more advanced R programming.

I find that some of the course materials are not sufficient for the learners to understand the concept in R programming and complete the assignment. The course could be improved by including more examples and hands-on exercises.

I think, as the last week, the first 3 weeks should have something more complicated to do. The
complexity level of the exercises grows exponentially on the last week of the course.

Great course! I gained a more in depth understanding of R and it's underlying structure. I did think there could more explanation given to object oriented programming R.

Excellent subject matter. 4 stars instead of 5 is only because there was no video. I love the videos in the other courses in this track, since I am an auditory learner.

the last peer review problem is much too hard for what I learned from the course material, if there is a more specific instruction for the assignment will be better.

The last problem is unnecessarily difficult with little related teaching and learning material provided. Otherwise, the course is certainly well worth taking.

It's really good practice for using R as a functional language, but
no video lectures makes student feel bored

Good course but the part of OOP is a little too simple, some extra in class exercises could improve this.

Good Course! But focus should be more on OOPs Concepts through video lectures to better understand it.

The last homework is ambiguous, and it doesn't have enough information available to solve it
