I think I once proposed, or at any rate once thought of, a -gt()-
function (those not familiar with old Fortrans can think "greater
than")
such that
gt(x, y) is 1 if x > y & x < . & y < . and 0 otherwise.
Similarly ge(), lt(), le() for >=, <, <=.
But I would be surprised at any enthusiasm for this. Everyone seems to
want to want to keep >, >=, <, <= together with "do what I mean".
That sounds useful! Then each could have there own gt function set to
function like R, or like SAS, or like Stata!
