[R] Function argument as string

[Vishwanath Sindagi]

Hi,

Suppose a write a function

a_fn<-function(arg1)
{

    return(table(arg1));
}

I have a column called AGE. Now I call the function c = a_fn(AGE);

When a_fn is called, AGE is received in arg1. My question is, how do I
access  the actual name of the argument arg1? i.e, inside the
function, i need to know that the actual name of arg1 is "AGE" in this
case.

Thanks in advance,
Vishwanath
