[Rd] export C++ array to R

Hi, I am a newbie on C++
Right now I have an array of doubles in C++.
Is there a way to "export" that array into R? Of course, I can allocate
the memory block first using "allocVector" and copying the array contents
one by one.
But, what if that array is fairly large? Copying doesn't look that
I was thinking of setting the data pointer(DATAPTR) point to that array,
and adjust the LENGTH of SEXP. But I don't know how to do that.
Any comment/answer would be much appreciated. Thank you.
