Is this what you want:
y = c(rep(2,5),rep(3,5))
ma <- data.frame(x = 1:10, y=y )
splitted <- split(ma, ma$y)
for (counter in (min(ma$y):max(ma$y)))
+ {
+ cat(counter, ":", splitted[[as.character(counter)]]$x, '\n')
+ }
2 : 1 2 3 4 5
3 : 6 7 8 9 10
But maybe this is what he really wanted:
> lapply(splitted,"[[", "x")
$`2`
[1] 1 2 3 4 5
$`3`
[1] 6 7 8 9 10
or even
> split(ma$x, ma$y)
$`2`
[1] 1 2 3 4 5
$`3`
[1] 6 7 8 9 10
