Thanks for all who got involved in my folly.
I have chosen the following path for now.
src <- '
int s = 7; // result of original oversize estimate before process runs
int c=3; //known column count established from a list argument (variable to
function)
Rcpp::IntegerVector v(s);
Rcpp::IntegerMat

If this is your goal, I
David,
One last thing: you are trying something difficult with large
multi-dimensional objects.
I really recommend that you try to become more familiar with a more STL-ish
way of doing things. Try something simpler on std::vector<> et al -- how you
can change dimension, expand, remove, ... witho

I have not been slack on reviewing the archives, but they ARE hard to
search.
So far, I am led to believe that a list of vectors can only be accessed
during initialization.
This would seem to be a real problem for entering elements in looped
increments 10's of thousands of times.

I want you guys to know that I appreciate all the effort that you put
into the Rcpp package and this list. I am obviously one of the early
people to hurdle the new "lowered bar" for C++ development in R.
I have developed a function that builds a series of vectors and a matrix
of undetermined size
