[ESS] eldoc in Rmd files

[Vitalie Spinu]

You have an outdated polymode

  polymode$ git show 0340f5e7e55235832e
  commit 0340f5e7e55235832e59673f027cc79a23cbdcd6
  Author: Vitalie Spinu <spinuvit using gmail.com>

Polymode has been rewritten and R functionality lives in a separate
package. Just install `poly-R` from melpa and remove *all* old polymode
configuration from your .emacs.
