Re: [O] [babel] Error when exporting a trivial org file to HTML: Wrong type argument: stringp, (results . "")

[Leo Alekseyev]

I changed the line to #+BEGIN_SRC R :results output silent :exports
none :var foo=0, but it gives me the same error as before.  Running on
the old-ish version of org (from January, commit
8be17c8c62a8fb402a2ebf1c963a4e9f8f5dec53).
