Ansari-Bradley test (PR#2252)
Full_Name: Wei Xu
Version: 1.5.1
OS: WindowsME
Submission from: (NULL) (63.215.238.92)
The P-value for a two.sided test is not consistent with the confidence
interval.
For example, P-value=0.1372, but the 95% CI doesn't include the H0 value(1).

Hello.
I sent an Email in r-help without answer for the moment.
I am wondering if it could have a mistake
in the code of the ansari.test function. For me, it seems that the function

small bug in ansari.test
The help page for ansari.test() says (emphasis added):
By default (if exact is not specified), an exact p-value is computed if both
samples contain less than 50 finite values **and there are no ties**.
Otherwise, a normal approximation is used.
However, this does not appear to be the case in R 2.4.1 or R 2.5.0. In fact,
even
example(ansari.test)
produces a warning

kernlab sigest
hello,
I have the following problem setting parameter 'frac' in the sigest
function of the kernlab package.

Could not compute QR decomposition of Hessian.
Hi,
I created the model below, which returns me the following warning message:
In sem.default(ram = ram, S = S, N = N, param.names = pars, var.names =

Ansari vs wilcoxon vs ks test
Hi all,
This is a statistics question, I hope someone out there will be able to help
me.
I have one population (oligonucleotide probes spotted on a Nimblegen array).
I measured "parameter one" (intensity after hybridisation) and I have
selected a subpopulation of the initial (one tenth of the initial) according
to a threshold value.
I now measure "parameter two" of

ansari.test (one tailed)
Hello.
I am probably wrong... I am wondering if it could have a mistake
in the code of the ansari.test function. For me, it seems that the function
do not recover the p value at the correct side of the normal law N(0, 1) when it
use
the normal approximation (presence of ties) in a one tailed test.

help in matching two column vectors
Dear list,
I have a long list of two vectors with some matching elements. I would like to line them up in two columns and have an NA in those positions of the second vector where a match is absent. With a simple example, I will explain my problem.
(a<-1:6)
(b<-c(5,2))
(m1<-match(a,b))
(ab<-cbind(a,m1))
m2<-numeric(length(m1))

Porting R
I am trying to get R 1.0 running on the Mac.
The main target is MacX. Anyone else working on that?
For the recent Macintosh system, I am trying to compile R using MachTen.
The R core compiles and runs without any changes, using the Unix make files.
The libraries give some problems, presumably due to handling of shared
libraries. It seems I am missing something to link. Before I spend my time

How to use a 'hidden' function directly?
I would like to be able to use two functions; qansari and pansari
which are found in the
function ansari.test. How can I evaluate these functions
independently? Thanks. --Dale
For example, when I load the function ...
qansari <- function(p, m, n) {
.C(R_qansari, as.integer(length(p)), q = as.double(p),
as.integer(m), as.integer(n))$q

ASTERISK PACKET ANALYSIS
Hi all, I've analyzed the packet stream resulting from a SIP session through Asterisk, and I found that Asterisk sends a lot of useless messages! In example, it repeats the three way handshake (invite-ok-ack) every time, also when it has just to forward the 'bye' message. Has anyone found the same srange thing?
thanks..

Problem logging into Samba

Got a srange problem and wondered if anyone could shed some light on it.

I have set all the users up and Linux users (red hat 7.2) and as smb user (had to do this manually though as smbpasswd -a didnt copy them across) and both users accounts

Problem with accessing internal variable in package.
I am writing a package, which contains several functions and variables.
The variables are for internal use by functions.
Functions are ment to be callable by a user.
However, the function cannot access these variables.
The package contains only R code, and was created using package.skeleton

because of the following 2 issues:
