I am trying to create a randomized matrix in R. It needs to be a presence/absence matrix, such that all values in the matrix are either 0 or 1. But I also need to specify row and column totals, for example, a 5x5 table where the row totals are: r1 = 4, r2, = 2, r3 = 3, r4 = 5, r5 = 3 and the column totals are: c1 = 5, c2 = 1, c3 = 5, c4 = 2, c5 = 4.
I was hoping to use r2dtable(), but I don't think you can force this function to use only 0's and 1's.
Are there any ideas?
Thanks!
I've tried using r2dtable() but end up with values higher than 1.
