Getting the name of a piped in argument

[lebryant]

I am trying to get the name of an argument that is passed into a function, and noticed the behavior changes depending on whether the argument is piped in or not.

library(tidyverse)

show_name <- function(data){
  substitute(data) %>% 
    deparse()
}

show_name(mpg)
#> [1] "mpg"

mpg %>% 
  show_name()
#> [1] "."

This allow happens with an rlang approach.

library(tidyverse)
library(rlang)

show_name <- function(data){
  as_name(enquo(data))
}

show_name(mpg)
#> [1] "mpg"

mpg %>% 
  show_name()
#> [1] "."

Is there a way to make this behavior consistent when piping in an argument.

Sorry, it looks like this was answered in this post. You can use sys.calls() to access the full function call.
