[ESS] ess, noweb and polymode

[Laurent ESS]

Hi Tyler,

Thank you for the idea, even if I would like to recover the 
ess-noweb-goto-chunk.

I installed swiper, ivy  and put the following lines in my .emacs.el:

(defun my-list-chunks()
   (interactive)
   (swiper "<<"))

(define-key polymode-map "g" #'my-list-chunks)

When I do M-n g I have the message:

my-list-chunks: Symbol’s function definition is void: swiper
