[ESS] List/menu of code chunks for Rnw files

[Gorjanc Gregor]

Hello to everyone!

R, Sweave and ESS are really great and they increased my performance as
well as reproducibility. Since Rnw files can become long I find it hard
to navigate through the file. Usually I am interested in particular
code chunk and I help myself with search, but you know ... Is there
any way to get a list o code chunks or beter imenu for chunks? I see R
functions and data in Imenu already, which is great. I tried to google
around but with no good result.

Thanks!

P.S. I have the following in my .emacs files relates to ESS.

(require 'ess-site)

;; Sweave - statistical reports
;;  http://www.ci.tuwien.ac.at/~leisch/Sweave/
(defun Rnw-mode ()
  (require 'ess-noweb)
  (noweb-mode)
  (if (fboundp 'R-mode)
      (setq noweb-default-code-mode 'R-mode)))
(add-to-list 'auto-mode-alist '("\\.Rnw\\'" . Rnw-mode))
(add-to-list 'auto-mode-alist '("\\.Snw\\'" . Rnw-mode))

(setq reftex-file-extensions
      '(("Snw" "Rnw" "nw" "tex" ".tex" ".ltx") ("bib" ".bib")))
(setq TeX-file-extensions
      '("Snw" "Rnw" "nw" "tex" "sty" "cls" "ltx" "texi" "texinfo"))

Lep pozdrav / With regards,
    Gregor Gorjanc
