dynamic array output by .C
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

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. -- Brian D. Ripley, ripley@stats.ox.ac.uk Professor of Applied Statistics, http://www.stats.ox.ac.uk/~ripley/ University of Oxford, Tel: +44 1865 272861 (self) 1 South Parks Road, +44 1865 272866 (PA) Oxford OX1 3TG, UK Fax: +44 1865 272595
