R's help system might be useful. www.rseek.org might be useful.
You haven't accomplished the second part of my response, and this
isn't a homework help list, so you'll need to do your own work from
here.

How would I go about saying the median = element x in terms of n (say (n + 1)/2 or whatever it would be) if there is an even amount of elements, or x in terms of n (with a different way of saying how many n) if there is an odd amount of elements?
