Hi.
The following may be close to what you require.
#prepare some data
dat <- expand.grid(v1=letters[1:3], v2=1:3)
dat
v1 v2
1 a 1
2 b 1
3 c 1
4 a 2
5 b 2
6 c 2
7 a 3
8 b 3
9 c 3
out <- split(dat, dat$v1)
#the first two groups are
out[[1]]
v1 v2
1 a 1
4 a 2
7 a 3
out[[2]]
v1 v2
2 b 1
5 b 2
8 b 3
Hope this helps.
Petr Savicky.
