This assumes, that the user knows elisp. For many customizations this is
necessary, but I would prefer a system where the user only has to
provide an R function which will be used. This offers less
customizability, but this would make it possible to use R to do the
customization. To write a new org-babel-R-assign-elisp-function would be
quite a challenge for an R programmer (like me...).
