Re: remoting ESS/R with tramp

[Tom Roche]

summary: when I add

(add-to-list 'tramp-remote-path 'tramp-own-remote-path)

to my init.el and restart emacs, I get

*Backtrace*
> Debugger entered--Lisp error: (void-variable tramp-remote-path)
>   add-to-list(tramp-remote-path tramp-own-remote-path)

The latter seems preferable. I currently have in my init.el

I appended

(add-to-list 'tramp-remote-path 'tramp-own-remote-path)

to the above, byte-compile-file init.el, and restarted emacs. But
restart abended with

*Backtrace*

What am I doing wrong? Again, locally, I have

* M-x emacs-version
> GNU Emacs 24.0.92.1 (x86_64-pc-linux-gnu, GTK+ Version 2.20.1)
> of 2012-01-11 on cw-bkp0, modified by Debian [2 times]

* M-x tramp-version
> 2.2.3-24.1
