[R] comparing 2 long lists in R

[Bert Gunter]

Also, in addition to what Sarah told you, have you checked on the
Bioconductor site, as this sounds like the sort of thing that they may

... and you've posted here often enough that you shouldn't still be
posting HTML and you should know about toy examples!

Cheers,
Bert
