Please avoid Nabble.... For starters, your mail has lost the original poster
and all context.
Anyways,
(A) in this particular case it wouldn't be the sum(x issue since it would stop
with a syntax error:
> sum(x
+ 1
Error: unexpected numeric constant in:
"sum(x
1"
>
More commonly, miscounting quote characters (' or ") is the culprit, or maybe a
curly brace {. The latter would stop at any syntax error, though:
> {
+ 1
+ q()
+ a b
Error: unexpected symbol in:
"q()
a b"
With quotes it will go on until a matching quote is found, since character
constants can be multi-line.
(B) More importantly, ESC is not invariably the ticket out. It is the case in
the Mac GUI and in RStudio, and presumably in RGui on Windows too, but in a
Terminal application on OSX or Linux, it is Ctrl-C.
