R help - Feb 2005 - stopping a function

I've looked for this information in all the R help sources I could find and
found nothing.  Is it possible to use some function key to stop the
execution of some R command without ending the R session (Windows, R 1.91)?
I've several times started functions that for various reasons are not
executing properly and it would be nice to stop them without killing the R
session.  I've been using taskmgr to end the R session but I then lose all
objects created during the session.

R 1.91 is not expected until 2050, if ever.

It's in the README, and for RGui, on the menus!

Esc in RGui, Ctrl-c in Rterm.

Not all computations are interruptible (most compiled code is not), but if 
they are, these will do it.

In Rgui, use the menu `Help' -> `Console' and look at the third line
from
the bottom.
