[R] Construct All Possible Strings from 4 Bases (ATCG)

[Gundala Viswanath]

Dear all,

Is there an efficient  way in R  to construct all  strings from 4 bases (ATCG).
If we want a length L string,  there are 4 ^ L possible strings of such.

e . g with L = 2 we have AA, AT, AC, AG, .. GC, GA, GT, GG as many as
4 ^ 2 = 16 strings,
with L = 3 we have as many as 4 ^ 3 = 64 strings
