Thanks, Hans,
That works for clearing the line. I should have looked at the NEWS for
the R.app GUI:
Last-update: 2011-12-22 [HJBB]
* In RConsole pressing the ESC key will invoke
"completion" as in standard application if no
R command runs including system(..., wait=TRUE)
otherwise pressing ESC key or STOP button will
try to terminate the running R command and, if
a system(..., wait=TRUE) runs, it will kill the
system command
but how about if I have an uncompleted command, i.e. with + prompt.
ESC used to jump out of that and it doesn't nor does ⇧⌘⇠ seem
to work? Thanks, again.
best,
Ken

I thought that this might be a Lion related issue as I updated
both my OS and R version at the same time but I see the problem
on an older machine running Snow Leopard, too. I can't give
an example. Just write a line of code and hit escape before
you hit return. This used to abort the command. Was this a
bug earlier that is fixed, or is it a feature that can be ...
Hi Ken,
yes - the ESC behaviour was slightly changed/improved.
Pressing ESC while R is EXECUTING R code including statements like
"system('foo', wait=T) will try to interrupt the R code AND kill
'foo' resp.
If R isn't executing something ESC invokes completion since this is
the standard Mac app behaviour.
You wrote: "Just write a line of code and hit escape before you hit
return. This used to abort the command."
Well, it did not abort the command since the command wasn't executed
yet, it only cleared the current command line buffer which differs
from the actual intention of pressing ESC => 'Interrupt current R
computation' I think.
To get the 'old' behaviour you can press ⇧⌘⇠ (standard short-cut to
select from cursor position to start of line) if your cursor is at
the end of the current line to select what you've already written
and start typing again.
Kind regards,
