I ran into an interesting oddity of R,
if (0) { print(1); }
else { print(2); }
is a syntax error, while
if (0) { print(1); } else { print(2); }
or
if (0) { print(1);
} else { print(2); }
is not. I presume it has to do with the duality of the newline functioning as an end of command (;) character, though it still seems a bit odd, and it took me a while to figure out what was wrong. I eventually figured out that to resolve this ambiguity, I would guess that ifelse() would be a preferred function.


I wanted to look up the internal R documentation for if via "?if", but this does not work. making the latter work would be a good idea.
