Yes, they've thought of that.

which(BEE == min(BEE), arr.ind = TRUE)

will do it.

Subject: [R] locating minimum value in matrix

Hi,

I have a matrix BEE and want to find the row and column numbers of the minimum value in that matrix.
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?

Thanks,

Gonšalo
