OK, it would be really helpful if you could let us know how we should
improve the documentation of it.

I'd suggest using :results output, and controlling the width of the
output with options(width=whatever) in R. E.g.
#+begin_src R :session babeltest :colnames t :results output
options(width=80)
summary(cbind(babeltest, babeltest))
#+end_src
#+results:
#+begin_example

I don't think either org or org-babel has any way to automatically wrap
wide tables. Also bear in mind the tranpose function in R (t), although
that's not helpful for this summary output, which is a rather weird
table, not a standard matrix or data frame.
