Dear R-help list users, I have a huge vector of numbers, how I can invert orden? For example x <- 1:10000000 I would like to obtain x_r <- 10000000:1 Thanks, Sebastian.

Oops. I have read the first ref returned by google and it happened to be tibco's doc, not the R's one. The layout is very similar hence my mistake. The latter does not

...ore; In this case, interestingly, you need one of those I think - almost everything I found online did not have the exact details. Peter Dalgaard definitely was right that Tukey did not use quantiles at all, and notably did *not* define the three groups via {i; x_i <= x_L} and {i; x_i >= X_R} which (as I think you noticed) may make the groups quite unbalanced in case of duplicated x's. But then, for now I had decided to fix the bug (namely computing the x-medians wrongly as you diagnosed correctly(!) -- but your first 2 patches only fixed partly) *and* go at least one step in the...
