[R] allocating memory in C, not in R

[S. Blay]

Dear R helpers,

I need to retrieve several vectors of various types from a call 
to .C(), but I don't know their length in advance. 
Is there a way to do this without allocating an excessive amount 
of memory? 
If so, an example would be very helpful.
