* lisp/ob-R.el (org-babel-R-initiate-session): Protect against use of
unbound variable `ess-ask-for-ess-directory´. The default for this
variable is true, so act accordingly if it is found unbound.
* lisp/ob-R.el: Remove initialization with `nil´ from
`ess-ask-for-ess-directory´ and `ess-local-process-name´. Remove
second declaration for `ess-local-process-name´.
* testing/lisp/test-ob-R.el (test-ob-R/simple-session): Bind
`ess-ask-for-ess-directory´ to nil to facilitate batch testing.
