I think you will find that 'set.seed' does give you the same random state each time. That you don't get the same result each time implies a bug in your code. Looking for uninitialized variables would probably be a good start. Using valgrind under Linux would most likely find the error quickly.
Also, using '<<-' is generally a bad idea.
