[R] Continuation and parse

[Philippe Grosjean]

Well, you haven't used the search engines with the right key: the magic 
words are:

 > RSiteSearch("incomplete line")

With the first document being my query (almost two years ago), and the 
second one being Peter Dalgaard answer. You must adapt it to cope with 
internationalization, but basically, you could use something like:

 > grep("\n2:",try(parse(textConnection("ls)")), silent = TRUE))
numeric(0)
 > grep("\n2:",try(parse(textConnection("ls(")), silent = TRUE))
[1] 1

Best,

Philippe Grosjean
