Dear all,

I dealing with a puzzle that I need some help. I have a data set where
I'd like to determine within "r" the most preferable choice (choice1
to n) as in the replication above.
So, there are three essential tasks: I need to tally the votes for
every id (number), I need to see if the number id with most votes has
at least 50%+ of all votes, and I need to discover who's the id the
the least amount of votes.
After performed these tasks in fly, I need to save the winner
information (r and which round choice), I need to proceed dropping id
got lesser votes in the first choice, but considering its second
choice vote. Test again if there is any id with 50%+ of all votes.
This procedure ends when any id gets 50%+ in each "r".

Daniel
