remove a list of specific values from another list

I am trying to remove a list of specific values from another list but I cannot find any resources to help me do so. 

list1 <- list("a","b", "c", "d", "e", "f", "g","h", "i", "j", "k")

list2 <- list("a","b","c","d")

list3 <- list1[-list2]

I would hope to get an output of the first list without a,b,c, or d. Instead I get

Error in -list2 : invalid argument to unary operator

We can use setdiff as the list elements have length 1

setdiff(list1, list2)

Or use %in% and negate (!)

list1[!list1 %in% list2]
