How to connect arithmetic operators using the R |> pipe?

edit

It is not possible to directly connect arithmetic operators using the R pipe (|>). The pipe is used to connect functions and pass the output from one function as the input to the next function. Arithmetical operations are performed within a function or by using the usual arithmetic operators (+, -, *, /) in R.

To connect arithmetic operations with the pipe, first, we need to perform the operations inside a function such as mutate or transmute from the dplyr package.

For example, suppose we have a data frame df with columns x and y. To perform arithmetic operations on these columns using the pipe, we can use the mutate function:

library(dplyr)

df %>%
  mutate(z = x + y,
         w = x - y,
         q = x * y,
         r = x / y)

In this example, the mutate function is used to create new columns z, w, q, and r with the result of arithmetic operations on columns x and y.

Alternatively, we can use the usual arithmetic operators to perform operations and then pass the result to a function using the pipe. For example:

df %>%
  transmute(z = x + y, w = x - y) %>%
  summarize(sum_z = sum(z), sum_w = sum(w))

In this example, the transmute function is used to create new columns z and w with the result of arithmetic operations on columns x and y. The summarize function is then used to calculate the sum of these columns.
