[R] tab complete for R under ESS/ 2

[S.McClatchie]

Tony

I appear to have been premature in my happiness over finding a 
solution. Everything was fine until I tried to load (C-C C-l) a dumped (C-c-
C-d) file. At this point I was passed to the debug buffer with the 
message:

Debugger entered--Lisp error: (void-variable replaced)
  (let ((errbuffer ...) error-occurred nomessage) ::: replaced with: (ess-
command (format inferior-ess-load-command ...) errbuffer) (save-
excursion (set-buffer errbuffer) (goto-char ...) (setq error-occurred ...) 
(setq nomessage ...)) (if error-occurred (message "Errors: Use %s to 
find error." ...) (if nomessage ... ...) (let ... ...) (ess-switch-to-ESS t)))
  (let ((source-buffer ...)) (if (ess-check-source filename) (error "Buffer %s 
has not been saved" ...) (if source-buffer ...)) (let (... error-occurred 
nomessage) ::: replaced with: (ess-command ... errbuffer) (save-
excursion ... ... ... ...) (if error-occurred ... ... ... ...)))
  ess-load-file-original("h:/DATA/TS.variability/R-
src/smc.allometry.by.species.2.R")
  (if (equal (ess-get-process-variable ess-current-process-name ...) 
(default-value ...)) (ess-load-file-original filename) (ess-load-file-
ddeclient filename))
  ess-load-file("h:/DATA/TS.variability/R-
src/smc.allometry.by.species.2.R")
* call-interactively(ess-load-file)
----------------------------------------------------

Even after removing the changes in ess-inf.el back to the original, 
saving, exiting emacs and restarting it, the problem remains. Not pretty.  
Can you help?

Thanks

Sam
