Is that what you need?

Hi Ben,
While Jean's answer looks correct, I think that there is something
amiss with your specification of the problem. You have eight
combinations in your "possibilities". So if you draw samples "x"
where:
If p(x = possibilities[1,] | possibilities[5,]) = 0.5 AND
p(x = possibilities[2,] | possi
Ben,
Perhaps I am missing something, but couldn't you simply reduce your
possibilities to:
possibilities[c(1, 5, 2, 4), ]
Var1 Var2 Var3
[1,] "A" "A" "C"
[2,] "A" "A" "T"
[3,] "C" "A" "C"
[4,] "C" "G" "C"
If you sample from these four rows you will have a 50% chance that Var1 and
Va
4 matches
