R 4.1.0 has been released and has a couple of handy new features.

One is a shorthand syntax for defining functions. Now, instead of writing, for example

triple <- function(x) x * 3

you can use the more concise syntax

triple <- \(x) x * 3

which may come in handy when using anonymous functions in `apply`

-type calls.

More interesting, though, is the addition of a native pipe operator to R, given by `|>`

, i.e. a pipe and a greater-than sign.
As of R 4.1.0, the following are equivalent.

triple(4) 4 |> triple()

This is similar to the functionality previously provided by the **magrittr** package (often through **dplyr** and **tidyr**):

library(magrittr) 4 %>% triple

but saves you loading any add-on packages.

In fact, there already was a pipe of sorts in base R, as John Mount points out: in the form of the `->.;`

‘operator’ (assign to a variable called `.`

, then terminate with the rarely-used semicolon):

4 ->.; triple(.)

As a result there are now four different ways of writing the same function call as a one-liner in R version 4.1.0:

triple(4) 4 %>% triple 4 ->.; triple(.) 4 |> triple()
