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!

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.

Good course for intermediate coders who are learning a new coding language. This course might be a little bit more difficult for beginner coders.

It's a great course. I just think the Programming Assignment used to be more dificult in reation to the contents of classes, but I recommend it.

highly complex, should have been a little slower pace

I think I have no right to complain as i not yet finished my swirl course . totally worthy

A great way to get into the vast ecosystem that is R! I learned a lot, but most importantly I learned enough to know how much I don't yet know.

I've learned a lot in this short course.

It's not for the faint-hearted to be honest. Many concepts are deep and hard to grasp at first sight

Very good course to start one's data science journey and build strong basics of R. Swirl module particularly was a very good way to practice.

Challenging, but rewarding. I have been using R for years, and this is by far the best course on R Programming that I have ever come across.
