Challenging but great fun and really helped me to get more familiar with R

swirl is very used in this course. It is one of the best tools to learn R

Nice course but it would have been better if more theory was covered.

Nice but the projects are way harder than the lessons and quizzes;

Nice course! Assignments could have been a little more challenging

The exploratory part was very good. But, PCA was a waste of time.

The plotting aspects of this course appealed to my visual sense.

This would be very effective for my personal skill enhancement.

More challenging Problem sets, as in the R Programming course !

High quality course, but the order of lectures is not perfect

Great overview, especially the parts on dimension reduction.

sorry, but I didn't understood much from 3rd and 4th week..

Really nice course! Great instructor and good case studies!

Thank you, i learnt a lot and will continue on my journey.

It was a great experience to complete such a good course.

Best course of the 4 taken so far in this specialization

Very good introduction to the various graphing systems.

Improvement should be done to the materials of Week 3.

Excellent course with great didactic. Congratulations!

Hopefully it could be clearer on dimension reduction.

Well crafted, carefully designed learning materials!

NIce course, but the lectures are a little tedious

Decent overview of the graphing fundamentals in R

Great and Excellent thoughts and course material.

Very detailed. Like the case study by Dr. Peng.
