For those who might be curious, the answer is that each of the R,
Cython and octave extensions aren't on by default, so you must first
do %load_ext <extension name> before using it.  We don't want IPython
start to be unnecessarily slow, so these things get loaded only when
the user requests them (esp. given that they need to import somewhat
unusual packages, and some even have to start subprocesses like R and
octave).

cheers,
