Re: [R] Nearest neighbour in a matrix

There's a general no homework policy on this list, but if you use apropos() with some fairly intuitive search terms the problem won't be hard at all once you hit the 'magic' function. You also might want to look at "?apply". After that, ask your TA... Sorry we couldn't be more help, Michael
