Hi everybody,
how is it possible to refer to an argument passed to a function in the
function call? What I like to do, is something like
f - function(x,y) x+y
f(2, x) # should give 4
The problem is of course that x is only known inside the function. Of course I
could specify something like
I think you'll have to code it a bit different. I'd do :
f - function(x,y){
if(missing(y)) y -x
x+y
}
f(2)

f(2,3)
