Helm-R

Hello,

It has been said (on gnu.emacs.help) that Helm-R is old (2012) and not
maintained anymore.

Are people still using it?

If yes, why isn't it updated anymore?  Because it just works (TM) as
expected, and because there aren't new needs?

If no, do you use something else instead?

Best regards,
  Seb

Documentation of thing at point

Hello,

I would like to be able to look up documentation of "thing at point"
with `info-lookup-symbol' (`C-h S' in Emacs Lisp buffers, and in all
modes for me...).

However, in my case, it does not return anything...
See http://screencast.com/t/sU27gqjr45.

Am I missing something in my configuration, so that the R documentation
can be integrated within a generic way to access it (other than `C-c
C-v' which is only usable in ESS buffers)?

Best regards,
  Seb

Listbox for matching previous commands

Hello,

Thanks for the tip about
comint-previous/next-matching-input-from-input. Very useful.

By accident, I discovered it was as well existing in RStudio, with the
key bindings C-up/down.

Though, there, it displays a listbox with the matched commands from the
history: see http://screencast.com/t/jOV9PjlGpc0H.

Is something similar doable in ESS?

Best regards,
  Seb

Copyright year in ess-autoloads.el

Hello,

Everytime I update ESS from MELPA, I get interrupted with the question:
"Add 2014 to copyright?", as you can see:

--8<---------------cut here---------------start------------->8---
Saving file d:/Users/fni/.emacs.d/elpa/ess-20140824.1452/ess-autoloads.el...
Add 2014 to copyright? (y or n) n
Wrote d:/Users/fni/.emacs.d/elpa/ess-20140824.1452/ess-autoloads.el
--8<---------------cut here---------------end--------------->8---

This comes from the following chunk of code in my .emacs file:

--8<---------------cut here---------------start------------->8---
  ;; update the copyright notice to indicate the current year
  (add-hook 'before-save-hook 'copyright-update)
--8<---------------cut here---------------end--------------->8---

because the copyright year in the `ess-autoloads.el' file is NOT
up-to-date:

--8<---------------cut here---------------start------------->8---
;; Copyright (C) 2012 Donald E. Curtis
--8<---------------cut here---------------end--------------->8---

Could you put an updated copyright?

Best regards,
  Seb

Re-execute the previous command with `!!'

Hello,

When trying to re-execute the previous command with `!!' [1], I get a prompt
that never ends.

See http://screencast.com/t/EjENuwrDgiw4

My fault?

Best regards,
  Seb

Pasted commands are not inserted in the history

Hello,

If I select a command from the source buffer (as a region) and press C-c
C-c, it's copied and run in the iESS buffer. Expected ;-)  All good so
far!

But if I want to edit it, I do <C-up> (for comint-previous-input)... and
I get the previous command which I manually typed in the iESS buffer,
NOT the one that has just been run...

See http://screencast.com/t/McqRXnqCqeM3 for an example.

Is this a bug?

How to access the last run command without having to select it as
a region in the iESS buffer, and copy/paste'ing it?

Best regards,
  Seb

Error highlighting in iESS

Hello,

I try to move away from R Studio, and go to Emacs ESS for interacting
with R.  The advantages are countless, needless to try to convince me!

Though, there are some things which I don't get as nicely as in
R Studio, among others the error reporting.

See http://screencast.com/t/reEu54obwPn.

Is there a way to get a similar highlighting in Emacs (i.e., the whole
paragraph, instead of just one or two words in red)?  Is it something
bad in my configuration?

Best regards,
  Seb

Interface to iESS

Hello,

FYI, I've read a post of Stefan Monnier explaining that he'd like to
standardize the access to Comit buffers.

See http://mid.gmane.org/jwvvbpld20s.fsf-monnier+emacs%40gnu.org.

Seems in-line with current key bindings, a.o.

Best regards,
  Seb

Previous/Next error in ESS tracebug

Hello,

I'm trying to use the debugging features of tracebug, but have problems
understanding how to use 'em all; in particular, I already have troubles
using next/previous error.

As you can see on http://screencast.com/t/VKapcfM8S7m, the only answer
I get (be it in the source buffer or in the iESS buffer) is:

- Before first reference, or
- Beyond last reference

What am I missing?

Best regards,
  Seb

Problem with transcript file

Dear all,

as my emacs skills are rudimentary I don't know what to do with this error.

I want to start recording a transcript file at the start of emacs ESS R session.
Hence, I set:

(load  "/usr/share/emacs/site-lisp/ess/ess-site")
(setq ess-ask-about-transfile t)
in .emacs.

Then I start up emacs (GNU Emacs 24.3.1), ess and specify the name of the transcript file when prompted for it
and this is what happens:

Loading /usr/share/emacs/site-lisp/ess/ess-site...done

Losing Mark in Knitr block

Hi All,

When I set a mark outside of a knitr/sweave block <<>>=  <at>  but then move in
to the block, the mark gets deactivated. Is it possible to disable this
behavior?

Thanks,

Rob
