 ## Creating tibbles
 
 Almost all of the functions that you'll use in this book produce tibbles, as tibbles are one of the unifying features of the tidyverse.
-Most other R packages use regular data frames, so you might want to coerce a data frame to a tibble.

 You can do that with `as_tibble()`:

 The main reason that some older functions don't work with tibble is the `[` function.
 We don't use `[` much in this book because for data frames, `dplyr::filter()` and `dplyr::select()` typically allow you to solve the same problems with clearer code.
-With base R data frames, `[` sometimes returns a data frame, and sometimes returns a vector.
+With base R `data.frame`s, `[` sometimes returns a `data.frame`, and sometimes returns a vector.

 ## Exercises
 
 1.  How can you tell if an object is a tibble?

 2.  Compare and contrast the following operations on a `data.frame` and equivalent tibble.
