If you have done the Data Science Specialization prior, this is a lot of review. It is good review though. If there were any skills that would be good to get repeat practice on, it would be these skills.

A very good course to read and get the valuable content of R language. This is for the students who want to learn and practice the basic and some intermediate concepts of data manipulation.

I really love this course as I have learnt many new R package in this course. Even if I have used R for almost 3 years, there are still many unknown things in R waited to be explored by me.

A thorough course that covers a lot of efficient data manipulation styles within the R environment. I learned a lot of neat tricks that help with quick analysis of large data frames.

Excelente curso para los que comenzamos o ya tenemos un poco de experiencia con R. Es necesario saber inglés, pero me parace que con un nivel intermedio no tendrás ningún problema.

The course is helpful for the R beginners. Learned a lot during the course, and the final week homework led me to review the past 3 weeks' lessons in a practical way. I recommand.

Good Practice..........!!!...really helpful for building data science concept through R Programming.........Really salute for hardworking of instructor..................!!!

Great course, and teaches the fundamentals. Google is your friend and websites like RFunction will supplement perfectly. Recommend the use of RStudio to work along course.

The assignment/quiz is one of the best I had for an online course. It is inspiring and informative. Thank you for providing such a pleasant learning experience.

The R Programing Environment is very supportive environment, and I appriciate the guideline and the materials. futhermore, the course was good begining. Thanks

What I liked most about this course was that it gave us a solid foundation on how to program in R and at the same time made us want to learn more about it.

Great Introduction, may we worth clarifying that for Data Manipulation the script must be saved before entering submit() as you cannot make progress.

Overall, it is an excellent course. However, there was a big difference in terms of difficulty between the quizzes, especially with the last one.

The course will be very helpful for those who are interested in R programming and starting it out. The course teaches you the basics.

very good introduction to the R programming language, with holistic introduction to updated R packages written by Hadley Wickham.

So far I have really enjoyed this course. It has added to my overall R knowledge, especially the functions for data manipulation.

Very nice courses for people want to get more familiar with R (like me), the quiz are really related to the points in the book.

Excellent R course for a beginner. This course is a bit more challenging, but you can learn a lot as a first time learner.

This course helped me learn functions I had not been previously aware of and really helped challenge me. I learned a lot!

Very useful course not only for beginners but also for practitioners! There are some valuable insights in the R practice!

Interensate, ameno y muy explicativo. La plataforma es muy cómoda y el ritmo de trabajo es asequible. Recomendable 100 %

An excellent course. Very good introduction to R and certain packages such as dplyr and grepl. Hands-on and challenging

Great introduction to the world of R !!! Also a great refresher course after taking the Data Science Specialization.

Very detailed with clear instruction of basics to a bit of advanced on R. A fantastic crash course for any beginner

Great overview of R with a focus on Hadley Wickham's tidyverse (very useful set of packages for data scientists).
