[R] R commandline editor question
I am using R 2.1 on Apple OS X.
When I get the prompt, I find it works well with emacs commandline
editing. Keys like M-f C-k etc. work fine.
The one thing that I really yearn for, which is missing, is bracket
matching When I am doing something which ends in it is really
useful to have emacs or vi-style bracket matching, so as to be able
to visually keep track of whether I have the correct matching
brackets, whether ( or { or [.
I'm sure this is possible. I will be most grateful if someone will
show the way :-) Thanks,

Re: [R] R commandline editor question
Hi Ajay
well ESS has such a facility.
However, I think Mathematica has a super scheme: unbalanced brackets
show up
in red, making them obvious.
This is particularly good for spotting wrongly interleaved brackets, as
in
([ blah di blah )]
note bracket closure is out of order
in which case both opening braces are highlighted in red: and the
system won't
accept a newline until the closures are all correctly matched.
Would anyone else find such a thing useful?
Could the ESS team make something like this happen?

I tend to write a lot of stuff on the fly at the R commandline. Yes, colours are a great way to deal with this, and this feature should ideally be in ESS. -- Ajay Shah Consultant [EMAIL PROTECTED] Department of Economic Affairs http://www.mayin.org/ajayshah Ministry of Finance, New Delhi __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
Re: [R] R commandline editor question
Of course it should be in ESS. In fact, it is for me, anyway
(different colors depending on whether they match or not).
Check out the paren-hilit or paren-match (or something like that)
customize options.
I.e.
M-x customize-groups ret paren spc
(which ought to complete on names of groups/options starting with
paren) or blink-paren.
(I'm not on an Emacs-enabled computer right now).
