R: intersection of list components

Question

In R, let q be a list with 100 components. Each component is a character vector:

i <-3
q[[i]] 
[1] "A" "B" "C" 
i <- 8
q[[i]]
[1] "B" "A" "D" "F" 

and so on. I would like to intersect the components q[[i]] , for all i . As output I just need those characters which lie in the multiple intersection. I only know the function

 intersect()

which works with 2 inputs and I don't really know Reduce . Is there any smart-quick way to do this?

I thank you very much!

Answer 1

Just try this .

Reduce(intersect,q)

And If you want to show intermediate result:

Reduce(intersect,q,intermediate=TRUE)
