R help - Jul 2009 - How to stop an R script when running JGR on a Linux/SuSE system

When I need to stop a running R script  on Windows or Mac I just use the
<esc> key which kills the current script and returns the control to R
interpreter.
But when I run R from JGR the <esc> is useless as well as the other
available keyboard keys.
Just recently not even clicking on the STOP-symbol (a big red X) placed on JGR
top menu bar could terminate a process that had entered a long loop.
Eventually I could kill the process from bash comman line using # kill -KILL
<process-id>
 
I wonder whether there is a more gentle way to stop an R script running on top
of JGR aother than ... unplugging the power cord.
 
Thank you so much,
Maura

there must be a bug in JGR on Lunux. Clicking the stop button should
stop the script, clicking it here on my linux machine will immediately
crash R together with JGR altogether. Unfortunately JGR still seems to
be the best (and only) available shell/editor combination available.
When running R in an ordinary terminal window execution can be
terminated with <CTRL>-C

I hope they will soon fix this (and a small handfull of other
bugs/flaws, mostly missing/wrong keyboard shortcuts) and JGR would
make a huge step from "very good" to "excellent"

I would like to add a few points to this list, some of them I personally
find even more annoying then some of them mentioned there:

- add the keyboard shortcuts <shift>-<del> and
<shift>-<ins> for the
actions "cut" and "paste" as an alternative to
<ctrl>-x and <ctrl>-c to
make it compliant with CUA and behave like virtually every other editor
in existance. (this is my most important concern, i use it all the time
when moving rearranging lines, being used to eclipse, SciTE, Kate, even
MS-Word, OpenOffice or notepad on windows, everytime i try to cut/paste
I already have a finger of the left hand on the shift-key (from
selecting the text) and it takes one or two seconds to realize that the
intended shortcut is missing and then move both hands to find the other
two keys on the keyboard)

- change the keyboard shortcuts for block-indent and block-dedent to the
more commonly used <tab> and <shift>-<tab>

- remove the restriction of a minimal window size for the console
window, allow the user to resize it as small as he wants.

- add a shortcut for "run all", this is the only menu item without
shortcut. <F5> would be a good choice as some other widely used
editor/shell combinations for other languages have similar functionality
on that key too (SciTE, IDLE, etc.), it seems to be some kind of
standard too.

I would even make the changes on my own (i probably would already have
done it) and supply patches if i only could find any hint on how to
build JGR from sources. (where to place the source files, what command
to start the build process and where to copy which files after
successful built to test them)

So this is another point on my list: write a small howto on how to
participate in development.

not at all!

How much is available depends on the platform,
but the first one that has been available for all platforms,
even before R existed, is  
     ESS  ( http://ess.r-project.org/ ),
an acronym for "Emacs Speaks Statistics".

But there are quite a few others (I do not really know from
personal experience), see, e.g.,
all the projects (listed on the left hand side) of
    http://www.r-project.org/GUI

I personally can recommend rkward which is now available on many
platforms and which is probably a little easier to use than the mighty
emacs+ESS.
