Dear list, Given a list of elements like: aa <- list(one=c("o", "n", "e"), tea=c("t", "e", "a"), thre=c("t", "h", "r", "e"))
Is there a function that returns the intersection between all? Both match() and intersect() only deal with two arguments, but sometimes I have more. Here, it should return "e" (or NA if none of the letters are common). I have a solution to apply %in% multiple times (here two times, first between the first two and then between the result and the third) but... perhaps there is a better and quicker way.
