Very Very Rigorous Course for a beginner on R language and because of its nature, after completing just one course, I feel like I have gained a lot of knowledge and also familiarity with R language.

A very good course to read and get the valuable content of R language. This is for the students who want to learn and practice the basic and some intermediate concepts of data manipulation.

The material of this course is useful. However, the swirl course that accompanies it is plagued with issues that date back YEARS (there are posts on GitHub and the course's discussion board from 3+ years ago with the same unresolved or barely patched issues. If I hadn't already been reimbursed for this course by my employer, I would've given up on day one.

If you are on Mac chances are that can't complete this course without some major hacking. There is a 3 year old bug (as of june '20) in the swirl package the course uses that still hasn't been fixed. Comments section is littered with people who gave up on completing it and nothing is being done. Not cool at all.

I had to drop out because of technical issues. A week 2 issue that is documented in the bulletin board had no clear resolution. After several months of trying to figure out the issue for weeks, I determined that the course wasn't worth extra time and money being spent.

The course doesn't prepare us well for the final exam. The expectations are too high for what is teached. I had to learn a lot by myself to complete it, which is not what I expect when I do a course. I don't recommend it to anyone.

You cannot complete one of the course assignments because swirl has a bug that prevents you from completing it. The bug has existed for years and has not been fixed.

Final assignment may not be reviewed for weeks. If you go on to capstone, issue could extent into months. Expect to use many external resources.

The classes are not super clear, and there really isn't much support for learners facing bugs.
