How can i select a set of element in a list ?

x<-list(1,2,3,4,5)

How can I create a new list which only have the last 4 elements of x.
I can do it with a loop, but I want to avoid that. Thanks!

example :
y<-vector("list",4)
for ( i in 1:length(y) )
    y[[i]] <- x[[ i + length(x) - length(y) ]]

y

[[1]]
[1] 2

[[2]]
[1] 3

[[3]]
[1] 4

[[4]]
[1] 5

Regards,
Julian
