[R] list of vectors which are part of an initial vector

Dear list users,
given for example the vector a <- c(1:5), which is the easiest way to create
a list of 5 vectors with three elements each apart from the head and the tail,
like

1 2
1 2 3
2 3 4
3 4 5
4 5

? I tried to use the "split" command, with no success. Could somebody
show me hints for an efficient way?

Thank you for your help
Stefano
