Re: [R] writing a simple function

Your code looks like matlab, but I don't see how it would work even there. The specific problem is the to refer to an array, you do so with square brackets [..] and not round ones, (though your v is not an array, anyway, so your troubles are just starting). Let's tackle what I think may be your p
