Hi r-experts,

I want to check if a certain argument has been passed on in a function call
via ...

ftest <- function(x1, ...) {
  if(hasArg(y2)==TRUE) print(y2)

Now I call the function passing y2 via ... but I cannot access or use the

ftest(y2= 2, x= 1) 

> error in print(y2) : object "y2" not found

What I am doing wrong here? How can I access the object y2?

TIA and Merry Christmas,
