Is there any simple solution to get ranks in descending order? Example, a <- c(10, 98, 98, 98, 99, 100) r <- rank(a, ties.method="average")
produces 1 3 3 3 5 6
I would want this instead: 6 5 3 3 3 1
What does that correspond to (why are 98 and 99 ranked the same)? I believe you want 6 4 4 4 2 1, which is length(a) + 1 - r, as well as rank(-a).
