Vocabulary
An important part of being fluent in R is having a good working vocabulary. Below, I have listed the functions that I believe constitute such a vocabulary. You don’t need to be intimately familiar with the details of every function, but you should at least be aware that they all exist. If there are functions in this list that you’ve never heard of, I strongly recommend that you read their documentation.
I came up with this list by looking through all the functions in the base, stats, and utils packages, and extracting those that I think are most useful. The list also includes a few pointers to particularly important functions in other packages, and some of the more important options().
