A workaround to use c()
with the pipe operator is to add curly brackets
library(dplyr)
mtcars %>% {
c(.$mpg, .$cyl)
}
But it's not pretty.
Is there alternative to the c()
function that works with pipes in R?
library(dplyr)
mtcars %>%
alternative_c(.$mpg, .$cyl) # Does such a function exist?

Using the magrittr
exposition pipe %$%
you could do:
library(magrittr)
mtcars %$% c(mpg, cyl)

An alternative is to pipe into with()
:
mtcars %>%
with(c(mpg, cyl))
