[Rd] dynamic array output by .C

[Tib]

HI,
from the examples of Writing R Extensions,  I see one still has to
declare the size of arrays by NEW_NUMERIC(n) or
allocVector(REALSXP,n), how can I extend arrays?

I know this question is a little specific, but it would be a lot
helpful if anyone can give me a  quick question. Thanks
