Re: [R] Quelplot
Hadley, I forwarded your request to Boris and Ken. Here is Boris' response. Rich Dear Richard: I looked a bit more and found the second edition of book referenced, Rand R Wilcox, Introduction to Robust Estimation and Hypothesis Testing, Second Edition, Academic Press, 2005. It has over 600 quotes on google scholar. If my memory is correct, Wilcox developed code for relplots and possibly quelplots.

Thanks Rich - unfortunately, as far as I can, tell Rand Wilcox only developed relplot code. Hadley On Thu, Sep 22, 2011 at 12:52 PM, Richard M.

The description is not particularly explicit, but the major/minor axes of the ellipse are defined in terms of standard scores for X and Y as Z1 = Y + X Z2 = Y - X If you can figure out what they mean by proportion of the total standard deviation due to residuals..., then something like P_1 = sum(Z_10) / n P_2 = sum(Z_20) / n Maybe Boris can help. Thanks for bringing this to our attention. If the bagplot is a totally non-parametric analog of a bivariate boxplot, the quelplot might be a 2df parametric version. -Michael -- Michael Friendly Email: friendly AT yorku DOT ca Professor, Psychology Dept.

Re: [R] Quelplot
Hi Hadley, Thank-you for your interest in the quelplot. I agree that Rand Wilcox only published relplot code. I do not know of any other R or S implementations. I wrote all of my code in HTBasic (Rocky Mountain BASIC) originally. I later copied some of it to SAS proc iml, but I think that was just the multivariate analog of the relplot (including the bivariate relplot). I wonder if there is a typo in the Technometrics article, because the quelplot always worked fine for me but I recall somebody else having trouble with programming it. I think I sent that person my HTBasic code back in the early 1990's. Perhaps that was Rand. I think I did send it to somebody who asked for it in Australia. I will have to search for my code. I know I have it on my PC in HTBasic format, but it has been a long time since I used it and may have to work a bit even to print it or to get it out into a DOS text file. I may have a DOS text file of it at home on a 3.5 diskette, but even if I could find it, I doubt if I could find a disk drive to read it! When I get it in a useable format, I can send you that code, or at least the parts of it relevant to the quelplot, if you would like it. Perhaps just browsing it would show the problem you are having with my Technometrics article, whether it was a typo or just something that I wrote poorly. There may just be a few subroutines that would need translating from HTBasic into R, and that when added to Rand Wilcox's library would give his software the quelplot capacity. Hadley, I took your R/Splus Fundamentals and Programming Techniques course 5 years ago in Washington DC, but have used R just a couple of times since. I've rarely programmed in R, but this would be a good project for me to start with. It may be a few weeks though until I can get started on any of this though, but I will keep you informed.
