Questions regarding R + Aquamacs + ESS

[johannes rara]

Hi (I did sent this post also to R-sig-mac, but I think this is the
right forum for this post),

I have few questions regarding R 2.9.2 + Aquamacs + ESS. I'm moving
from WinXP to Mac (Snow Leopard 10.6.1) and also from Tinn-R to
Aquamacs (1.8c).

1. Is there syntax highlighting in Aqaumacs? Now when I open .R file
only the lines starting with comment mark (#), quoted words etc. are
shown in color. What about R:s reserved words? In Tinn-R these words
where shown blue. Is there this kind of functionality in Aquamacs?

2. When I evaluate an area of R code (send it to R), I press C-c C-r.
If the area is e.g. 50 lines, I would like that the cursor in the ESS
windows goes into an end (like pressing C-c M-r) and I don't have to
jump back into the code window. How can I achieve this?

3. It seems to bit complicated to keep pressing C-c all the time, is
there a way to make a shortcut key (e.g when pressing Alt-S an area of
code is sent to ESS-window (into R)

4. Is there a way to split code window and ESS-window (R) vertically
(side to side)? The default split is horizontally.

Thanks!

-Johannes

ESS has more font-locking (syntax highlighting) than what you see;
unless you are wedded to Aquamacs, have you tried the version of Emacs
built by Vincent Goulet:
  http://vgoulet.act.ulaval.ca/en/ressources/emacs/mac 

this should work nicely.

sure, this falls into the general issue of rebinding keys; e.g.

(defun my-ess-hook ()
  "Add my keybindings to ESS mode."
  (local-set-key (kbd "C-j") 'ess-eval-line-and-step)
  )
(add-hook 'ess-mode-hook 'my-ess-hook)

change C-j and the function you want to sit on there accordingly.
 


I'll leave others to fill in 2 and 4!

Thanks. Should this function to be included in customizations.el or which file?

I found an answer to my question number 2:

I included these lines of code to customizations.el

(setq comint-scroll-to-bottom-on-input t)
(setq comint-scroll-to-bottom-on-output t)
(setq comint-move-point-for-output t)

don't know what u mean here.  marking (C-space) and going down or up
creates a block, and hitting C-c M-r should send the code and take you
to the R session window.

this is one of the features of emacs.  try C-x 3.

hey johannes,

i guess i understand your question number 2.  when sending code via
C-c M-r, sometimes the cursor doesn't go to the end of R session
buffer.  i had the same problem since using emacs 23.  i placed those
comint variables in my .emacs file and the cursor is going to the
bottom now.  this works for me, thanks.

You may be used to it (Tinn-R's behavior) but note that R
has practically *NO* reserved words (*) and Tinn-R colorizes
(AFAIK, I'm not using it) several thousand of function names,
from 'base' and 'stats' .. packages.
These are not reserved in the strict sense, and with a
system as R and the 2000 CRAN+bioconductor packages, it's not
clear what names you should consider part of the language, and
which to be "user extentions", e.g., should 'lmer' be colorized
(Emacs language "fontified") or not?

Should the fontification happen for all standard + recommended
packages (but e.g., 'lme4' is not among those), or rather
for all objects that are currently visible in search() ?

In the end, I quite like the fact that ESS does not fontify too
many of these..
