Say I have a variable taking on a large number of values and I am only
interested in finding out how much each of the top five or ten values
represent in terms of frequencies. Is there an obvious way to tabulate only
the largest (or smallest) values of a variable? -tabsort- will do it but
generate tons of unwanted output (beyond the top values), I am more after
something like Nick's -extremes- but for frequencies.
