This course roughly follows "Advanced R" by Hadley Wickham. This book is worth reading cover to cover if you want to be a master R programmer.

I don't see how [ ] or [ ] would do partial matching. It is looking for an index integer. Besides that partial match such as A[["ma"]] might confuse someone reading the code.
