Well, I don't see why you need the CTRL-R functionality when you can
just as rapidly and efficiently using SEARCH functionality in scripts
too (CTRL-F in most applications, CTRL-S in emacs etc).
BTW, I am quite familiar with Unix, Linux and Sun Solaris and what
CTRL-R does (yes, I used it frequently). Which is why I am able to tell
you that CTRL-R will pull up all matching commands - even commands that
had failed! At least in a script environment, you tend to correct failed
commands. So you know when you search scripts, it will likely be the
correct command.
To summarize my view, I feel that CTRL-R is appropriate for shell
operations where one codes on the fly while using a search functionality
and scripting is appropriate for a scientific programming software.
Anyway, here is how to do what you want:
1) Install bash on your Windows machine - You can use cgywin. Or
download and unzip http://www.steve.org.uk/Software/bash/
2) Make the directory to bash.exe and R.exe are in your PATH variable.
3) Start -> Run -> cmd
4) Start R.exe
and now you should have your CTRL-R functionality (along with ls and
other bash goodies). Yes, I know you asked about Rgui.exe and not R.exe.
But this is the best I can do.
By all means go bother the R developers (most of whom I suspect are on
the mailing list). I will be interested in what they say.

Perhaps I was not so specific enough in what I want, for those not so
familiar with unix commandline featuers. I'm looking for the 'reverse
search' functionality where you hit CTRL-R, then start typing a bit of text
and it finds previous commands with that bit of text, which you just hit
enter to execute.
I already do write tons of code/scripts in R (using Emacs in fact!). But
one of the great features of R/SPSS/Matlab/etc is that they are interactive
environments. Thus, I spend lots of time issuing commands as well as
writing code. I want to be able to search back through those commands as
rapidly and efficiently as you can in the unix (and R unix) commandline.
Another way to think about this is -- the unix commandline environment is a
scripting environment where you can use emacs. Yet users of unix love the
CTRL-R functionality anyway (they wrote it!).
So, any suggestions to help do what I specifically asked, or should I go
bother the R developers?
thanks,
Mike
