using the name of an argument in a function
Hi all,
In a function, I need to get the name of a variable that has been used to
call the function.
For example, I want:
--- 8< ------
toto <- 3
fun <- function(y){
nameOfY <-deparse(substitute(y))
cat("name is ",nameOfY)
}
fun(toto)
# [1] name is toto
--- 8< ----
But deparse(substitute(y)) does not work all the time, especially when we
use generic function.
