Hi, Richard and Duncan:
Thank you both very much. You provided different but workable
solutions.
1. With Rgui 2.11.1 on Vista x64, the escape worked, but neither
ctrl-c nor ctrl-C worked for me.
Why did you expect them too? Ctrl-C is documented to implement 'Copy'
(the standard Windows shortcut). (Did you mean Ctrl-Shift-C by
'Ctrl-C' as distinct from 'Ctrl-c'? I don't think that works
anywhere.)
As Duncan said, Ctrl-C works in Rterm, and in almost all other R
implementations (the Mac R.app GUI is the only other exception I know:
it also uses Escape).
This is documented in the README (called something like
README.R-2.11.1 in the binary distribution) and in the rw-FAQ Q5.1.
Maybe it would be a good idea to refresh your memory of the basic
documentation?
2. The TCLTK version works but seems to require either more
skill from the programmer or more user training than using escape under Rgui
or ctrl-g/c under Emacs.
Best Wishes,
Spencer

How can one interrupt the following gracefully:

In R2.11.1 under Emacs+ESS, some sequence of ctrl-g, ctrl-c
eventually worked for me. Under Rgui 2.11.1, the only way I've found was
to kill R.
Suggestions on something more graceful?
This is an Emacs+ESS bug. In the Windows GUI or using Rterm, the standard
methods (ESC or Ctrl-C resp.) work fine.

Beyond this, what would you suggest to update a real-time report
when new data arrives in a certain directory? A generalization of the
above works, but I'd like something more graceful.
Thanks,
Spencer Graves
