I am not sure if I like the approach you used in the commit.

-        (unless (listp (car value)) (setq value (list value)))
+        (unless (listp (car value)) (setq value (mapcar 'list value)))

In the above, you are transforming (val1 val2 val3 ...) list into
((val1) (val2) (val3) ...).

Does it make sense from the point of view of R code?
AFAIU, the current ob-R implementation converts lists into R tables,
which is not accurate? Would it make sense to convert Elisp lists into R
lists directly?
