Hi All,

I have two vectors of alleles stored as DNAStringSetLists. For each element
in both lists, I need to find the length of the intersecting set. Using
mapply() and intersect() take too long, as does sapply(dna.set.list,
as.character) (and then using mclapply or lapply to find intersect on
characters). Is there a fast way to do this? I have vectors ~12 million
rows long.
