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!

Really interesting course. The interactive coding sessions with swirl are especially useful. Would be great, if you provided sample solutions for the programming assignments, in particular for week 4.

Assessments always seem a bit more challenging than initially expected and the learning continues. Assessments are not of the 'check the box' type. Well done.

I found this course challenging but very interesting and useful! Still in the dark mostly about the true purpose of lexical scoping in practical situations.

Swirl exercises are simply brilliant! Perhaps you can add more challenging problems

The assignments push you to research, which I think is a major plus point

Great course! R syntax can be tricky, and it often took a bit of googling and experimentation to complete the exercises. But I also learned a lot doing so.

I am working as BI and using R almost every day.Thank you for this course.

I can say that it very powerful tool for data analysis, especially big datasets.

Excellent course. May be difficult for individuals with little to no programming experience. The programming assignments are fun and will teach you a lot!
