Dear R helpers, I have a largish matrix (1300 x 1300) and I wish to find the row and column numbers that identify particular elements whose values I know in advance (for example, the row and column numbers for the maximum value of the matrix). I have looked in the help manual and found the functions 'row' and 'col' for finding the indices of a matrix. But, I can't figure out how to use them to obtain the indices of the matrix element with maximum value, despite over an hour of trying! Many thanks for your help, Jonathan Williams
