Yes. Use outshine.el with outcommented Org-mode headers. Here is an
example:

For editing the property-drawer of the first headline in full Org-mode,
use outorg.el. 

This is how the *outorg-edit-buffer* looks after doing C-u M-# M-#
(outorg-edit-as-org) on the first headline (to convert and edit only the
subtree at point, use M-# M-#):

[ups, I see a bug ... sources should be wrapped into #+begin_src R blocks]

For headline (1-8) and many many keyword searches in ESS/R use
navi-mode.el, here is the summary of the keyword searches:

,----------------------------------------------
| [KEY] : [SEARCH]
| ================
|                         a : ALL
|                         f : FUN

|                         x : OBJ
|                         b : DB
|                         X : objects
|                         Y : methods
|                         R : inout

|                         W : dataselection
|                         M : math

|                         _ : strings
|                         : : datestimes
|                         P : plotting
|                         L : lowlevelplotting
|                         T : trellisgraphics
|                         ~ : modelfitting
|                         S : statistics
|                         D : distributions
|                         { : programming
|                         = : assignment
|                         U : environment
`----------------------------------------------

You can combine headline and keyword searches like this:

,------
| C-3 D
`------

shows headlines up to level 3 and R-keywords related to distributions.
