[R] Finding an index of matrix[i,j]

[Wolfgang Viechtbauer]

I hope somebody can help me out with this. Let's say I have a matrix with
i rows and j columns and I want to find the index of the row AND column of
the maximum value in the matrix. I tried to play around with the which()
command, but couldn't find an easy solution that didn't involve loops and
various other inelegant approaches. I hope that there is an easy way of
doing this. Thanks in advance for any suggestions!
