Accessing columns, rows, or cells via $, [ [, or [ is mostly similar to regular data frames. However, the behavior is different for tibbles and data frames in some cases: [ always returns a tibble by default, even if only one column is accessed. Partial matching of column names with $ and [ [ is not supported, and NULL is returned.

We will use them in the tidyverse to replace the older outdated dataframe that we just learned about. In R, vectors are the most common data structure. In this book, we’ll often represent vectors like this: Each orange cell represents one element of the vector. As you’ll see, different kinds of vectors can hold different kinds of elements.

Use options(tibble.print_max = Inf)to always show all rows. options(tibble.width = Inf)will always print all columns, regardless of the width of the screen.

they don’t change variable names or types, and don’t do partial matching) and complain more (e.g. when a variable does not exist).
