The first thing I'd want is quantile() with weights --- which I
personally find quite interesting and have wanted several times
in the past --- not wanted enough to implement though.
I'm interested to hear of (or even see C or R implementations of)
fast algorithms for "weight quantiles".
Code contributions are welcome too..
(And yes, I do know that boxplots are base on "hinges" rather than
quartiles but that's less interesting here.)
