[R] replication time series using permutations of the each "y" values

Dear All,

I'm trying to create this:
I've these data (a, b,c, etc. are numbers) :

1  a b
2  c d f
3  g
4  h
   ...
N

I'm trying to create the all "time series permutations" (length = N)
taking account
the possibilities for each value. For example (N=4),

1  a
2  c
3  g
4  h

next,
1   b
2   c
3   g
4   h

next
1   a
2   d
3   g
4   h

and so on. For this example, there are 2*3 different (possibilities)
time series, but
I need to do, v. gr., N = 100, and 2^14  different (possibilities)
time series. I am wondering
if somebody could give me a hint (suggestion) to make this using a
function in R.

thank you so much

best regards
