R help - Feb 2010 - Help with "split".

I read in the documentation for split:

?split? divides the data in the vector ?x? into the groups defined by ?f?. 

But I am still unclear as to its function. Take for example:

x <- 1:4
split(x, c(0,1))
$`0`
[1] 1 3

$`1`
[1] 2 4

I am not clear on how this result is reached.

Thank you.

Usual recycling rule: Same result as split(x, c(0,1,0,1)).
