I have two data frames. Suppose the first has rows

r1
r2
r3

and the second has rows

R1
R2
R3

I'd like to generate the data frame:

    r1   R1
    r1   R2
    r1   R3
    r2   R1
    r2   R2
    r2   R3
    r3   R1
    r3   R2
    r3   R3

How would I go about doing this? I'm sure there's a clean way to do it
but I find myself thinking in loops.
