There are no common subexpressions that optimize recognizes in R0, so
it actually works in both cases, despite the warning message.
You can see that it doesn't recognize the common subexpressions in R0
by trying optimize(args(R0)). I don't know why it considers "matrix"
a special form; I'd think it could treat it like any other
