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
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.
