Hi, I need some help with this one: how do I check whether a vector is already present in a list of vectors. I have seen %in% recommended in a similar case but that obviously does not work here. c(1,2,3) %in% list(c(1,2,3), c(4,5,6)) returns [1] FALSE FALSE FALSE which makes sense since 1, 2 or 3 are not elements of that list. I don't really know how to move from there though. Best wishes, Marcin
