Can you be a little more concrete? If you want the form of the expression given (rather than its value), deparse(substitute()) will work:
fnc1 <- function(x){ deparse(substitute(x))} fnc1(3) # 3 fnc1(x) # "x" fnc1(x + 4) # "x+4" If you are passing them through the ... argument, you can coerce that to a list and use the names() attribute. If you want to reconstruct the exact call (e.g., for a modelling function), match.call() will do it.
