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
Use lengthgets().

Greetings,
I am building a stochastic simulation model in a C++ shared library
for R. My model will generate a random number of new observations and
also delete some old observations, however, the numbers cannot be
predicted before the computation engine runs. For simplicity, I am
trying to control my programming at the second stage (pure C++ for R).
It seems .C accepts fixed size of arrays as input (also ouput), can I
modify size of array for deleting old and adding new observations in
.C?
No, but .Call can.
