For example, `df %>% split(.$var)` is equivalent to `split(df, df$var)` and `df %>% {split(.$x, .$y)}` is equivalent to `split(df$x, df$y)`.
You can use `.` the left-hand side of operators like `$`, `[[`, `[` (which you'll learn about in Chapter \@ref(vectors)), so you can extract a single column from a data frame with (e.g.) `mtcars %>% .$cyl`.
With `%>%` you can use `.` on the left-hand side of operators like `$`, `[[`, `[` (which you'll learn about in Chapter \@ref(vectors)), so you can extract a single column from a data frame with (e.g.) `mtcars %>% .$cyl`.
A future version of R may add similar support for `|>` and `_`.
For the special case of extracting a column out of a data frame, you can also use `dplyr::pull():`
