Excellent course! I already knew a lot about R - but this class helped me solidify what I already knew, taught me lots of new tricks, and now I have a certificate that says I know `something' about R!

"R Programming" forces you to dive in deep.\n\nThese skills serve as a strong basis for the rest of the data science specialization.\n\nMaterial is in depth, but presented clearly. Highly recommended!

GREAT for learning the BASICS of R. Nothing too advanced. Definitely need further classes to use R for anything useful that cannot be done in Excel.

This course is great, but the assignments are harder than I expected, it seems that there are not enough connections between assignments and lectures.

High level of difficulty, which met my expectations.

Really challenging to complete, but simultaneously excellent for an induction into the R package.

The last assignment was very tough, not for the faint of heart. There were some useful methodologies in the discussion forums but it was not enough.

Great introduction to R. Maybe not for beginers.

I have learned a lot. Esasy sort videos with just the necesary things to advance in r programming.

Course is good but I found the assignments to be a little complex than the course's content. Although it's altogether a great learning experience.

The instruction for the GITHUB is very unclear. I was confused with the 40 digit hash number so it would be great if you can revise that exercise.

This is an excellent course, however, you need to dedicate at least 3 hour a day to complete it in one week if you have experience in programming.
