Please supply example code of what you are trying to do, and what the 
difficulty is. As I mentioned, there should be no problem in generating all 
the random variables at once, as R generates the same values if you do it in 
chunks or all at once, but the latter method is much faster.

(The example code should be runnable without us having to have access to any 
private or undefined dataset. The example code you mentioned in your first 
post contains many undefined variables, and it is not clear what it is 
trying to accomplish.)
