 But it's not right.  This is one statement, and it returns the value 3:

 1 +
 2

 This is an error:

 1 + ; 2

 The semicolon is a statement separator, not a line return.

 Technically speaking a semicolon is a statement terminator, not a statement separator. In the case of the R language, that is a "nit". In the case of Pascal, it is a big difference.

 This is one reason why I _always_ use the semi-colon. It is _never_ really wrong to do so. It may be _unnecessary_ in some case. It is also why I always use <- as the assignment operator (well, that and because I like it from my APL background). If there are two ways to express something, and one of them is _always_ correct whereas the other _might not_ be correct in some cases, then I think doing the former is simply "better form". But, then, I'm anal about other things to. And that doesn't apply to interactive use. I don't terminate my interactive statements with a semi-colon all the time. Just most of the time. Of course, I'm a touch typist too and so it is not really much of a problem for me.
