comment How the command dist(x,method="binary") calculates the distance matrix?
But the proportion of bits in which only one is on amongst those in which at least one is on is not the same as the ratio of the symmetric diffetrence to the union, is it? The latter has as as denominator the size of the full set, while the former has as denominator the size of the set of bits in which not both are "off"?
