Thanks Andy; you have found an issue that we need to deal with; there
is currently no inferior-R-args variable that I can see, nor is there
is an inferior-Splus-args as the appendix might suggest.
The closest variable I could find is:
(setq inferior-ess-start-args "-q")
but that is currently overwritten in the call to inferior-ess:
(defun inferior-ess (&optional ess-start-args)
...doc string says:
"Takes the program name from the variable `inferior-ess-program'.
An initialization file (dumped into the process) is specified by
`inferior-ess-start-file', and `inferior-ess-start-args' is used to
accompany the call for `inferior-ess-program'. "
but then in the call to R, ess-start-args is normally "--no-readline"
and therefore the following line will obliterate the current value of
(if ess-start-args (setq inferior-ess-start-args ess-start-args))
Ess-core: my suggestion is that we change this line to something like
(concat inferior-ess-start-args ess-start-args)))
and update the appendix so that there is no mention of
"inferior-Splus-args" if that is no longer used.
