Difference Between R: wilcox.test and STATA: signrank
This is my first post to the mailing list and I guess it's a pretty stupid
question but I can't figure it out. I hope this is the right forum for these
kind of questions.
Before I started using R I was using STATA to run a Wilcoxon signed-rank
test on two variables. See data below:

problem getting R 2.3.1 svn r38481 to pass make check-all
Hi,
I noticed this problem on my home desktop running FC4 and again on my
laptop running FC5. Both have previously compiled and passed make
check-all on 2.3.1 svn revisions from 10 days ago or so. On both these
machines, make check-all is consistently failing (4 out of 4 attempts on
the FC 4 desktop and 3 out of 3 on the FC 5 laptop) in the
p-r-random-tests tests. This is with both default

Improvement of [dpq]wilcox functions
Hi,
I believe I have significantly improved [dpq]wilcox
functions by implementing Harding's algorithm:
Harding, E.F. (1984): An Efficient, Minimal-storage Procedure
for Calculating the Mann-Whitney U, Generalized U and Similar
Distributions, App. Statist., 33, 1-6
Results on my computer show (against R-2.9.1):

rank of a matrix
how do I check the rank of a matrix ?
say
A= 1 0 0
0 1 0
then rank(A)=2
what is this function?
thanks
I did try help.search("rank"), but all the returned help information
seem irrelevant to what I want.
I would like to know how people search for help information like this.

anomalous result for wilcox.exact in exactRankTests
Hi,
In the exactRankTest package, I've become aware that you can get
anomalous p-values (i.e., above 1) from the wilcox.exact method, as in:
> wilcox.exact(c(-0.6,0.8,-0.5))
Exact Wilcoxon signed rank test
data: c(-0.6, 0.8, -0.5)
V = 3, p-value = 1.25
alternative hypothesis: true mu is not equal to 0
This is disturbing. Has anyone encountered this before, and if so

Possible ld.exe problem when building
Dear R People:
I am trying to build R-2.5.0 from source on a Windows machinee.
I downloaded the tools and such, and started things off.
I received some odd errors messages, looked on the R Search
and found a similar problem. The suggestion was to re-load
"ld.exe".
I downloaded and installed everything again. Same problem.
I am including my output.

Bug in wilcox.test
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

Errors in wilcox family functions
Hi Everyone,
Following the previous discussion on optimizing *wilcox functions, Andreas Loeffler brought to my attention a few other bugs in `wilcox` family functions. It seems like these issues have been discussed online in the past few months, but I haven?t seen discussion on R-devel...unless I missed an email, it seems like discussion never made it to the mailing list. I haven?t seen any bug

psignrank and pwilcox null pointer deref (PR#1149)

Cell or PS3 Port
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

packages with FORTRAN code
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.

problems compiling R-0.63.3 on alpha
Hi again !
Thanks for the info on updating the config.site file which I
have done. I have also added -lm in the Makeconf manually
because this is needed explicitly for DEC cc.
However, there are still a few problems when linking some
of the files as you can see from the enclosed log.
Ciao,
Andreas

R-0.63 is released
I've put up R-0.63.0.tgz up for FTP from Auckland some minutes ago.
As usual, don't get it from there unless you are desperate, but wait
for it to be mirrored at a CRAN site near you within a day or two.
For those who *are* desperate, I've left a copy in
ftp://blueberry.kubism.ku.dk/pub/R-devel/R-0.63.tgz
(Be gentle, that's my desktop PC!)
