Dear all It sounds an easy task, but I got stuck with creating all possible contigency tables if the total count is fixed. For example, if the total count is 2, and number of cells in the table is 4 (nrow=2,ncol=2), there should be 10 possible tables: 0 0 0 0 0 0 0 1 0 1 0 2 1 0 1 0 1 1 2 0 0 2 1 1 2 0 0 1 1 0 0 0 0 1 1 0 0 0 0 0 And, are there any suggestions on creating hash and inverse hash function such that whenever we know the index integer, we can find the corresponding table? Please let me know if you have any thoughts. Thanks a lot!
