[R] Interrupt R?

[Spencer Graves]

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.


             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
