Very challenging, but good course. I've been programming in R for over a year, but there were still some things for me to pick up in this class. Assignments were a challenge, but satisfying to tackle.

"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!

It is not a beginner friendly course. Learn R from somewhere else and then take this course.

I'd say good if you are well versed in R already BUT for me...a little too much too soon.

Not very clear instructions. It can go above the head at times. SWIRL part is the best.

Demanding. The peer reviewed task in week 3 is not adapted to the material content.
