Vitalie,

anything-c-source-occur is in
http://www.emacswiki.org/emacs/anything-config.el , so it should be
brought in with (require 'anything-config).

occur (http://www.emacswiki.org/emacs/OccurMode) lists all lines of the
current buffer that match a regexp that you give it. I use that more
than standard search. You can highlight parts of your file then jump to
them; it's great for highlighting object usage in a buffer. You should
be able to type "M-x occur" to try it. The item above lets you do the
same thing through anything.

That's already implemented. In an R buffer, look for the menu Imenu-S.
anything-c-source-imenu gives you the same access through anything
(though mine seems a bit broken -- there are several variations here
that I need to try: http://www.emacswiki.org/emacs/AnythingSources#toc1
).

Yes, that's possible. It would also be nice to get an rdired-type view
with a more information on objects besides just the name. When I have
time, I'll explore.
