## Loop to Fill dmax and dmin
for(i in 1:nsim) {

I filled the dmax and dmin with the distance values I calculated,
but what I really want to fill them with are the rows in G. What
should I do? I tried "which" function but it did not work. Thank you
in advance!!!!
Dear qq5011 ... AKA user1033763;
The practice of cross-posting questions to StackOverFlow and rhelp
within hours of each other is deprecated, at least on on rhelp.

If you don't get an answer within some reasonable interval (measured
in days, not hours) then feel free to post a follow-up ... with
citation of the first posting.
