Yes, they've thought of that. which(BEE == min(BEE), arr.ind = TRUE)
will do it.

The command which(BEE==min(BEE)) returns only one value which, I take, is the position of the minimum in a vector with as many elements as the matrix. Is there a quick and simple way of getting row and column numbers?
