Worth it. The final assignment was a great challenge, the course seems to cover some good concepts of R, and provide a good base for those looking to learn even more.

Learnt a lot in R especially Lexical Scoping, Datatypes, vector operations, loops and apply commands. I would recommend this course to all my friends and colleagues.

Good course to start off your R Journey. It is guided and has enough validation mechanisms to reinforce your learning. Thanks John Hopkins Team to put this together.

The course provides a good explanation on important concepts of R and the assignments are designed well to hone the Programming Skills needed to tread Datascience.

A systematic learning journey of programming, a very new area for me, still need to improve confidence with more practice on this subject. Thank you to all of you.

Very good introduction to programming in the R language. Programming assignments were fun and structured very well to reflect the concepts learnt from the lessons.

I really liked the course, I learned new things that I did not know.

I will continue with the rest of the courses in this series

Thank you Johns Hopkins University

This course was exceptionally informational and it did upskill and that's saying something because I had applied to a lot of courses but this gave me what I needed

Really useful course. I strongly recommend to spend time on the programming exercises, specially is is long time since your last programming task (e.g. > 10 years)

I had experience with R in a class at my university, and I learned a lot in this course that my class didn't cover. The assignments were more challenging as well.

It was a great course for understanding and using R for basic package. I would like to thank builders of swirl package for such and awesome module for teaching R.

The lectures, swirl modules, and assignments had very high synergy for a multi-faceted learning experience. The pinned posts in the forums were extremely helpful.

The level increases very very fast. For people starting from scratch (as me) will take the to complete the assignments. Challenging, but overall of great quality!

Very good course. It helped to understand the basics and good practice, and helped me in doing research experiments in R using UCI dataset for my research paper.

Exellent for beginner.

I literally didn't know anything about R, and was not familiar with programming.

This course gave me a step for advanced data programming.

Professor is very well rounded and is quite enjoyable to hear his voice! Keep up the great work, looking forward to the next sections of the data science series.

Very hard course but very useful, I think, lecture videos totally disconnected from the assignments. One will have to dig deep to understand the basic concepts.

Great course to get to know inside and out R programming and not just for quantitative analysis (for me) but also getting to know how R used across other users.

The course was very well taught, and I got to learn a lot of things from this course about R Programming. As this course developed keen interest in me about R.

Excellent basic course, although I understand that people with no previous programming experience might struggle with it (and even some old programmers like me)

It's great to learn it from here. However, for beginner like me, it was a pretty complicated while doing the assignments. But, thanks anyways for the teachings.

An excellent course to get to know the basics of R programming. The practice material and the assignments really instill the material being taught in your mind.

Thank you very much for everything you learned.

It is these difficult times of the Pandemic. Thank you very much for your generosity in sharing your knowledge.

The course was great! The only thing that was a bit difficult was the caching in R. An introductory video on this topic would be very beneficial. Best regards
