[R] Abrupt closure of R when using .C function

[Nouedoui Laetitia]

Hi Everyone,

This is my first message on this discussion list.
 
I create a R function which includes a .C function. I didn't get any 
error neither from "C side", nor from "R side". I tried to put proper 
type in R.

But the problem is that I get an abrupt closure of R, with the following 
message: " R for Windows GUI front-end encountered a problem and needs 
to close " .

Does anyone have an idea about where this abrupt closure come from?

Thank you.
