8) Command completion and contextual help in R. The first one is
probably fairly easy. The second one is probably impossible. It would
involve giving out detailed help messages when things go wrong. Not
sure how to do that.
Doesn't ESS do this?
Isn't this too automatical answer? I don't use Emacs and believe I'm not
the only. But it is not the core problem. Why to connect as important
basic (in my opinion) interface feature as command completion (at least)
is with using a special text editor? In Octave, database interfaces and
others command completion is a standard. So what's the reason not to
include it in R?
No, I don't think it's automatic, it's very reasonable. I'm not
quite a fan of (x)emacs-ESS, but it must be recognized that
it is much easier learning and using (x)emacs-ESS
than developing the command completion feature. I think that
an open source project such as R must take advantage
of other open source projects whenever this is possible. If the
command completing feature exists in emacs-ESS, let's use
it there. Geting too big could kill R, because any new feature
implies maintainance and documentation. Therefore, I understand
that the R-core team focuses on developments that either
do not exist in other packages or that exist in packages that
cannot be easily linked to R.
