The last exercise was excellent (Week 4). Each question exposed the chinks in our code. This challenged the learner to refine the code to plug all holes. However, what I am not sure is how effective is my coide against failures and against speed.

the assignments might be a little bit difficult for beginners to start with but that is what which will trigger a hacker in you and in turn will compel you find the answers and explore new and innovative ways of solving highly convoluted problems

You can learn basic functions of R and do practical assignments on your own. However, the assignments are a little bit challenging, and students need to take some time to figure it out, especially for people who are not familiar with programming.

Undoubtedly the best course on Coursera! This course is great fun, challenging, and loads of learning! I highly recommend this course to all the learners! Thanks to the instructors and the Johns Hopkins University for such a magneficient course!

Very useful course for beginners and intermediate users of R. It gives some very important insights about the infinite potential of this programming language. Definitely recommended for people who use R for professional and/or academic reasons.

Great introductory course in R. Swirl is a very good introductory method for learning R by 'doing it'. The set of exercises were great (allow us to explore R in a more deep level), with very detailed and easy to follow instructions. Recommend!

Excellent introduction to R Programming...whether you are taking it stand-alone, as part of the data scientist specialization or want to ease into the machine learning side of things . The swirl() exercises are a helpful add. Kudos to the team.

This course provides a great overiew to introductory R programming. Since taking the course, I have successfully used the precepts learned here for a number of analysis projects. Coupled with ggplot2 graphics, the results became self-evident.

REALLY THIS COURSERA VERY HELPFUL TO ME AND I GAIN LOT OF THINGS I HAD LEARN IN THIS PLATFORM .WHERE I HAVE IMPROVE MY SKILLS AND R PROGRAMMING IS A BEST WAY TO LEARN IN THIS PLATFORM .ASSIGNMENT ARE VERY HELPFUL TO ME WHILE DOING THE COURSE

A good course to start with the fundamental and there is no better way than to learn hands-on which the assignments do help with. Would recommend for beginners as the videos cover a lot of topics. Improvements can be made but i like the course

Great course. But please consider including a reading version of the video lecture, (not the same as the transcript) just like in the previous course (The Data Scientist Tool Box). I found those reading versions of the lectures really useful!

Great course, I loved the SWIRL module. It was awesome. The videos were great and the examples really well though. The instructor has a great voice, he should consider a side job as a narrator, he could do it great.

Honestly, I just loved it.

I like this course so much.just because when I was doing this course I have learnt so many thing that will help me in future and thankyou so much sorry for giving me this opportunity.i will surely do more course and learn new thing from you.

This course will provide you with fundamental knowledge about R. It does not only teach you how to do things, but why to do them and it also covers how R works behind the scenes. This is valuable knowledge for anyone wanting to work with it.

It was a nice programming course to start with although did not have prior skills in programming. I believe that I will use the knowledge to improve my programming skills and hopefully become a data scientist and an expert on R programming

This course was set out in such a way that it was very easy for me to follow. I hope that all the courses in this Specialization will be as well planned and structured as this one. It was very easy to learn the very basics of R programming.

Excellent course ! i aready know about R but this class very help me .i learn a ot of R basic , but i was completely lost for week 2+ 4 write functiom assignment - they strike at the level too high level for complete tye beginner for me

This course is easy at the beggining. And difficult at the end. I try to do it at least 2. I will recommend it to all the people who would like to get knowledge in programming and in data science. To these who are curious about the world.

Great course! I got previously some basics in R and this course helped me a lot with more effective programming in R. Especially, thank you for great lectured "functions" module, because I never understood it and now it seems much easier.

It´s an excellent course, please take in mind that the effort necesary to finish this course is bigger than the effort applied in the previous one, The Data science´s Toolbox, but the knowledge obtained is very pertinent to data analysis

Indubitably a great starting point for someone who is new to R programming language. The course curriculum is so intutive and well decorated such that it was a challenging task for someone like me who belongs to a CS graduate background.

The best part of the course is swirl. It allows me to refresh my concepts at any point of time as the library is installed in my system. Apart from that this course has a very refined structure which has avoided complexity and confusion.

It's help alot for gaining confidence in my R programming skills. I don't say that it is not for the beginner, but they will need more time, effort and motivation to finish this course. Thanks, Coursera and Roger Peng for the insights!

Really loved the assignment. I wasn't familiar with R before, but the complexity of the assignments made me dive deep.

I don't know too much about data science. But, I think in the real-world scenario I will face these type of problems.

An amazing course! I have had some experience programming in R but this course helped me take my programming to the next step. I highly recommend this course for any level of programmer. It is a great course to have in your back pocket.
