Moreover, setting the seed once, then evaluating two functions means you are
sampling from the same distributions, but you do in fact have different values.
Outliers in the rarefied tails of the distribution may lie quite considerably
off the expected diagonal. Try
set.seed(123)
qqplot(rbinom(n=1000, size=1000, p=0.05),
rbinom(n=1000, size=1000, p=0.05))
and you will find that you approximate the "1 clear line" quite well - for most
of the values.
