Re: [R] search through a matrix

row() gives the row number of each element of the matrix, similarly col() gives the column number. By definition, diagonal elements are the elements correspond to same row and column numbers. That's how it works... x <- matrix(1:12, 3, 4) > x [,1] [,2] [,3] [,4] [1,] 12963 [2,]
