[R] input a list into a function

[Don MacQueen]

It works for me, without changes. See below.

But I can recreate your error if I type the plus signs at the 
beginning of second and third lines. For your example, don't type any 
plus signs, except for the one in
    print(g[i]+x)}

By the way, nothing that you did fits the description "input a list 
into a function", because you haven't created any lists (your "g" is 
not a list).
