In particular, `org-babel-R-write-object-command' contains an R
function that processes the object for `:results value'. The guts of
it is a call to write.table(). Here is an example:
#+NAME: show write.table
#+BEGIN_SRC R :results output
write.table(c("a","b"))
#+END_SRC
#+RESULTS: show write.table
: "x"
: "1" "a"
: "2" "b"
The difficulty is that write.table() coerces its first argument to a
`data.frame', whence the odd seeming row/column labels.
Making the R code in `org-babel-R-write-object-command' smart enough
to do what the OP wants without breaking stuff might be possible if
anyone wants to do the work.
However, IMO `:results output' is the way to go for such cases. There are
plenty of tools in R for formatting output and the user will have better
control over what is produced.
