[ESS] Problem with Rd-preview-help

I am using ESS 13.05 with Emacs 24.3.1 on Windows, Vince Goulet's
I am trying to preview a .Rd file, using C-c C-p or M-x Rd-preview-help.
I get an error:
Warning in file(con, "r") :
cannot open file
Error in file(con, "r") : cannot open the connection
This used to work some time ago, but hasn't been working now for a
while. I have just ignored it but was encouraged to think I might be
able to sort it out by using the function debugging Vitalie helped me
with recently. (Use C-u C-M-x on the function and step through with
'n'). However when I go to Rd-preview-help in ess-rd.el, issue C-u
C-M-x, then invoke Rd-preview-help, the debugger fails to operate, and I
just see the error above. I also tried to run a back trace as in Section
16.2 of the manual but no *Backtrace* buffer appeared.
I suspect this to be another Windows command line 'feature', because of
the presence of lines
(setq shcmd (format "%s '%s'" Rd-to-help-command file))
(format "Rd-preview-help: (shell-command |%s| t)" shcmd))
(shell-command shcmd t)
C-h v Rd-to-help-command gives
Rd-to-help-command is a variable defined in `ess-rd.el'.
Its value is "R CMD Rd2txt"
I can process the .Rd file from emacs with
M-! R CMD Rd2txt filename.Rd
and get what seems to be the same result as I obtain on linux, so it
doesn't seem to be a path problem.
