List becomes vector list becomes vector list vector

Multiple vectors intersect
If there is 3 A list of genes is stored in R Vector , here intersect(intersect(A, B), C) You can take the intersection of the three ; If 10 A list of genes ？ 9 Layer nested intersect I'm afraid it's embarrassing , Write a for Circulation is also troublesome , Reduce Function is very convenient , Probably

genes <- Reduce(intersect, list(A, B, C, D …))
