Intersection of more than two groups in one function?
Here's a brute-force approach:
"%i%" <- intersect x1 <- c(1, 3, 4, 7) x2 <- c(3, 7, 8) x3 <- c(7, 1) x1 %i% x2 %i% x3

From: Ken Termiso Hi all, As far as I can tell, the only canned way to do an intersect between two vectors of ints is the intersect(vec1, vec2) function -- is there another function I'm missing for intersecting more than two vectors?? TIA, Ken
