Where, Peter? In R, or in ESS? As far as I can tell, this is new
behavior by R which has broken ESS (at least at Matthew is using it).
We do check for the existing file, as the description shows below:
;; Three options:
;; (1) Pop to an existing buffer containing the file in question
;; (2) Find an existing file
;; (3) Create a new file by issuing a dump() command to S
;; Force option (3) if there is a prefix arg
and if you dump from the current source, of course it overwrites,
since that's what you asked it to do, and since R apparently nukes the
comments, you don't get them again.
Of course, this is why the preferred philosophy for using ESS is to
treat text as the truth, and .Data/.RData contents as realizations
(possibly with small error) of the truth :-). One suggestion is to
force all ESS dumps (C-c C-d) to a directory called something like
.Rsrc (to be concurrent with .RData), and so all local (editable) data
will be relative to the .RData in the same directory.
