[R] Odp: Generating unque patient IDs

[David Winsemius]

Unfortunately the "rounding effect" (which I assumed was related to  
the automatic conversion from integer to numeric) is only going to  
show up above 2147483647L, so I question whether you really  
demonstrated a solution to what I understood was the fundamental  
problem.
