I frequently use the dplyr piping to get a column from a tibble into a vector as below
iris %>% .$Sepal.Length
iris %>% .$Sepal.Length %>% cut(5)
How can I do the same using the latest R built-in pipe symbol |>
iris |> .$Sepal.Length
iris |> .$Sepal.Length |> cut(5)
Error: function '$' not supported in RHS call of a pipe

%>% is called the forward pipe operator in R. It provides a mechanism for chaining commands with a new forward-pipe operator, %>%. This operator will forward a value, or the result of an expression, into the next function call/expression. It is defined by the package magrittr (CRAN) and is heavily used by dplyr (CRAN).
Use %>% to emphasise a sequence of actions, rather than the object that the actions are being performed on. Avoid using the pipe when: You need to manipulate more than one object at a time. Reserve pipes for a sequence of steps applied to one primary object.
The new pipe in R 4.1 It cuts down on external dependencies, so developers don't have to rely on an external package for such a key operation. Also, the built-in pipe may be faster. By contrast, grepl() in base R has the opposite syntax.
In RStudio the keyboard shortcut for the pipe operator %>% is Ctrl + Shift + M (Windows) or Cmd + Shift + M (Mac). In RStudio the keyboard shortcut for the assignment operator <- is Alt + - (Windows) or Option + - (Mac).
We can use getElement().
iris |> getElement('Sepal.Length') |> cut(5)
