(a very helpful answer to Georg's question; thanks, Sean!)
I've seen example code like this in many places,
and I'd like advocate a more readable alternative
x <- rbind(c(1,1,1, 2,2,2)
c(1,1,1, 1,1,2))
{efficiency really not being of any concern;
we are talking about didactical examples}.
I believe rbind() -- and indenting ("white space"
in general!) should be used much more for matrix construction --
because of quick "visual validation"
at least for small examples.
{and if you'd use ESS (http://ESS.r-project.org/),
a simple <Tab> key press automatically indents the 2nd line correctly!}
