Hi Matthieu,
My understanding (and I may get clipped up alongside the head if I'm 
wrong) is that R concatenates all the source code into one big file hen 
checking and the number is the line number in that file. The error 
message may mean that you have an extra right parenthesis in that line 
(or very near to).
