I took some time and liberty and tried to improve existing implementation of SignRank functions in R. (dsignrank, ...) As I have seen they've been based on csignrank. So I modified csignrank and, I believe, improved calculation time and memory efficiency. The idea is basically the same. I use the same recursion as original author used with one slight modification. I am generat...

There is a fairly new bug in wilcox.test in R-2.2.1 (stable). It wasn't there when I last taught nonparametrics in fall 2003. Line 86 of wilcox.test.R achieved.alpha<-2*psignrank(trunc(qu),n) It should be achieved.alpha<-2*psignrank(trunc(qu)-1,n) If you don't see why, decode the cookbook instructions p. 56 in Hollander and Wolfe (2nd ed.) or see http://www.stat.umn.edu/geyer/5601/examp/signrank.html#conf or just do a sanity check: does this to the right...

...o just fix these cases, but I haven?t dug super deep into the codebase yet, so I?m not completely sure how difficult that would be. Details and examples: - https://aakinshin.net/posts/r-hodges-lehmann-problems/ - Discussion in DescTools (https://github.com/AndriSignorell/DescTools/issues/97) 3. `*signrank` functions hang for large values of `n`. The exact value varies, but tends to be around `n>=1000`. `wilcox.test` supports an `exact` argument?should an inexact approximation be implemented for *signrank functions with `n>=1000`? An Edgeworth approximation could be similarly leveraged here to...

Hello, I am interested in optimizing some of R's vector math functions to utilize the SPE units of the Cell processor (commonly found in the Playstation 3) and I am wondering if anyone has already done any work in that area. I can't find anything using the search page or Google. (Admittedly it is difficult to search for information on a one-letter-named programming language whose

Recent sensible changes to the dynload mechanism have made an old problem resurface: how should we deal with packages which contain Fortran code and may need to be linked against additional libraries such as -lf2c? The current consensus is that extra Fortran libraries maybe needed are handled via the make variable FLIBS, and that `-lf2c' or `-lg2c' are added by default if g77 is used.
