The pipe shortens code and results in fewer variables because you do not have to save intermediate steps. Once you get used to the idea it is useful. Note that there is also the |> pipe that is part of base R. As far as I know it does the same thing as %>%, or at my level of programing I have not encountered a difference.
Tim -----Original Message----- From: R-help <r-help-boun...@r-project.org> On Behalf Of Sorkin, John Sent: Tuesday, January 3, 2023 11:49 AM To: 'R-help Mailing List' <r-help@r-project.org> Subject: [R] Pipe operator [External Email] I am trying to understand the reason for existence of the pipe operator, %>%, and when one should use it. It is my understanding that the operator sends the file to the left of the operator to the function immediately to the right of the operator: c(1:10) %>% mean results in a value of 5.5 which is exactly the same as the result one obtains using the mean function directly, viz. mean(c(1:10)). What is the reason for having two syntactically different but semantically identical ways to call a function? Is one more efficient than the other? Does one use less memory than the other? P.S. Please forgive what might seem to be a question with an obvious answer. I am a programmer dinosaur. I have been programming for more than 50 years. When I started programming in the 1960s the only pipe one spoke about was a bong.
