That's valid, but is it "correct form"? The semicolon at the end is not needed. I'd say it's a bad idea to use one, because it might give a mistaken impression about the meaning of something like

  a = 1

      + 2;

It's better to avoid semi-colons whenever possible, to make sure the C parser in your brain throws an exception and lets the R parser take over.
