Feature #3647

Updated by Yusuke Endoh over 3 years ago


Array#sample does not support sampling with replacement directly, so we must write codes like the following to obtain samples with replacement.

samples_with_replacement = n.times.map { source.sample }

If Array#sample has the argument for switching with/without replacement, we can write it as follow.

samples_with_replacement = source.sample(n, true)
