not a solution to your question, but these days hardly call R anymore,
but use wdired-change-to-wdired-mode. It has a shortcut since emacs
23.1 (Ctrl+x Ctrl+q). (for me, i just aliased it to “rn”).

this lets you rename current file or any file, and directly in dired
(as opposed to the tiny line in minibuffer). When done, just press Ctrl
+c Ctrl+c. To cancel the rename, press Ctrl+Esc.

this mechanism also replaced my use of rename by regex (% R), because
once in the wdired mode, you can just do normal regex replace.

if you use wdired, it can solve your problem too, since you can rename
by find/replace all files, which will also rename the same named
backup files.

warning: there was a bug in emacs 22. If you rename a file to the same
name (e.g. swap 2 files), it will end up delete one of them.

for emacs newbs, i've wrote some tutorial on renaming files here

Kinda funny how it took so long for Emacs to discover that directories 
are editable beasts.  Meanwhile, other Operating Systems like Win32 have 
been editing file names for ages.  GNU is *not Unix*.  We forget that to 
our own detriment.

haha. Are you being sarcastic? ☺

 Dired can edit file names one at a time, just like OS. Wdired lets
you edit names of multiple files at the same time as if it's a text
file. This feature isn't in Windows, Mac, Linux.

No, I was being serious.  I was trying to point out how buying into the 
Unix way of doing things can block us from doing the right things.

Dired allowed you to *rename* files, which is not the same as editing 
file names.  Sometimes, I work with some long file names for which 
renaming - the Unix way - isn't the right solution.  People that have 
used DOS, or its predecessors like CP/M, TOPS-20, TOPS-10 etc., know of 
better ways of doing it.

Yes, Wdired is a great advance.  I agree fully!  That is what GNU and 
Emacs are all about: making advances in user interfaces and building the 
right tools for the right problems.

I still have no idea what you're talking about.

Editing file names -- you mean like in word, or a Notepad file, in the
middle of a sentence?

Or do you really mean editing a filename, and when done, the
name of the file on disk has really changed?

Heck, I used tops-20 ("twenex") for years, and never heard of
what I think you're talking about.

Please elaborate a bit.

Thanks!

Well, thanks!

First I heard of it.   (On pc, I use xp.)

How to do it?

Thanks!

One problem with (the really cool) wdired is that after you
do your renaming, deleting, etc, you can't do "g" and still
be in a dired (wdired) of that same set of files -- it
has to kill off the wdired and go back to a regular
dired.

I think such an option would make sense for `rename-file' itself.  And
it should handle any kinds of backups Emacs recognizes.

dired rename backup file too

[Kevin Ryde]

When renaming a file with dired "R" (dired-do-rename), I'd like it to
rename the backup file too.  So foo -> bar and foo~ -> bar~.  Is there a
secret option or other command to do that?

I only use the single foo~ backup style, not the numbered backups, if
that makes it easier.
