Hi Ryan,
You're getting this result because five of the rows in a.one.qtr are
duplicates, as a results of sampling with replacement:
length(which(duplicated(a.one.qtr)))
[1] 5

Hi,
Why do you need to merge them? c.one contains what I think you want,
and then you want to randomly select 25 rows from that without replacement:
c.one <- cbind(c.one, a.qtr = sample(c(rep(TRUE, 25), rep(FALSE, 75
> head(c.one)
unique length age a.qtr
649649 71 4 TRUE

write post or give me some help.
I have drawn a 100 samples from a fictitious population (N=1000), and then
randomly selected 25% of the
