I don't know whether this will end up fitting into your setup, but
there's an emacs function `ess-execute-screen-options' that does what
Dan just suggested on a per-session basis taking the width of the
current buffer into account.  Even if it doesn't help with org-bable, it
makes life in ESS much pleasanter.

You can also look at the latex() function in the R package Hmisc and the
function xtable() from the R package xtable.  For data frames, matrices,
and some common summary functions, these functions will create a latex
table out of your R object.  Maybe Dan can suggest how latex code
generated in R could be properly included and typeset in org-babel.
