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

DescTools::Quantile
It looks like a homework assignment. It also looks like you didn't read the documentation carefully enough. The 'len.out' argument in seq is solely for specifying the length of a sequence. The 'quantile' function omputes the empirical quantile of raw data in the vector 'x' at cumulative probabilit(y)(ies) given in the weights' argument, with interpolation I'm

simultaneous confidence intervals for multinomial proportions: sample size
Hello!
I want to calculate simultaneous confidence intervals for a nominal variable with three categories: "yes", "no", "partially" and I expect that far more than 5 samples fall into each category.
I have read that Glaz & Sison's method is only appropriate for variables with 7 or more categories. Therefore, the Goodman method seems like a good idea.
I have

How to test the difference between paired correlations?
Hello,
I have three numerical variables and I would like to test if their
correlation is significantly different.
I have seen that there is a package that "Test the difference between
two (paired or unpaired) correlations".
[https://www.personality-project.org/r/html/paired.r.html]
However, there is the need to convert the correlations to "z scores
using the Fisher r-z

How to test the difference between paired correlations?
Thank you, but this now sounds more difficult: what would be the point
in having these ready-made functions if I have to do it manually?
Anyway, How would I implement the last part?

Hodges-Lehmann EXACT confidence interval for small dataset with ties
Dear r-helpers,
I have a small dataset (n<50), and I want to compute the Hodges Lehmann
exact confidence interval.
So far, I know that "pairwiseCI" has the function "HL.diff". The description
is as follows :
HL.diff calculates the Hodges-Lehmann confidence interval for the difference
of locations by calling wilcox.exact in package exactRankTests ;

wilcox.test point estimates perverse (PR#1150)
The point estimates produced by wilcox.test are perverse (not wrong, just
brain damaged). The Hodges-Lehmann estimator that goes with the signed
rank test is the median of the Walsh averages. The Hodges-Lehmann estimator
that goes with the rank sum test is the median of the pairwise differences.
wilcox.test agrees except that it uses the following very peculiar definition

Hodges-lehmann test and CI/significance
Does anyone know of an implementation in R of the Hodges-Lehmann
nonparametric difference between two groups? I am interested in the
estimate of the difference and the CI or significance of that difference. I
did some quick searching and didn't see it, but I may not have been looking
for the right name, etc.
Thanks,

Generating Hotelling's T squared statistic with hclust
I am doing a cluster analysis with hclust. I want to get hclust to output the Hotelling's T squared statistic for each cluster so I can evaluate is data points should be in a cluster or not. My research to answer this question has been unsuccessful. Does anyone know how to get hclust to output the Hotelling's T squared statistic for each cluster?

code for functions in base package
Is there any way that I can see the step by step code for functions in
the base package? For instance the dexp function. I am a student
working on writing my own function for something that is similar to
this dexp function and I would like to see the step by step code.

boxplot with average instead of median
I really like the ease of use with the boxplot command in R. I would
rather have a boxplot that shows the average value and the standard
deviation then the median value and the quartiles.
Is there a way to do this?

A9 Scheduler
Hi,
I am having some trouble understanding the scheduling scheme for the C-A9.
Looking at the ARMScheduleA9.td file I find this line that overrides the
target SchedWrite with processor specific latencies.
def : SchedAlias<WriteALU, A9WriteALU>;
However, in this same file, I find the lines presented below, which are
mapping the SchedReadWrite to, for example, the ANDri instruction.

Need Help Getting Windows XP To Use Samba Properly
Hi everyone, new to the list.
My apologies if this issue has already been covered, but I am having the
following problem with Samba:
Using Windows XP as a client, I am trying to see a Solaris system as a
server. Solaris is running Samba 2.4.2, and Windows 2000 sees it as a
server without any problems.
Windows XP, however, generates the error "The network name is no longer

partial autocorrelation for Rt vs. Nt-1, ......., Nt-h
Dear list, following a previous querry we are still stuck!
As pointed out by Erin Hodges the "ts" library includes a PACF function
which reports the partial correlation of population density at time t
against lagged population density.
However, what we are trying to calculate is the partial correlation between
rate of population change, Rt=log Nt/Nt-1, against lagged population

Incorrect placement of an instruction after PostRAScheduler pass
Hi,
I’m facing a crash issue (--target=arm-linux-gnueabi
-march=armv8-a+crc -mfloat-abi=hard) and debugging the problem, I
found that an intended branch was not taken due to bad code generation
after the Post RA Scheduler pass. A CMPri instruction after an
INLINEASM block (which inturn contains a cmp, bne instruction) is
being moved before the INLINEASM block incorrectly resulting in two

Unfortunately we're not able to install more software of radically change any configurations. We also do not use LDAP (just a workgroup, hosts file, static IPs and Samba). But those are good ideas, I'll keep them in mind just in case. Major thanks.

Problem with compiling OpenBLAS to work with R
I believe that repo just follows the directions on my blog. Without seeing
Dr. Hodges?s code, my initial concern is the many references to Cygwin. My
method specifically does not use Cygwin but MSYS2 and Mingw64/Rtools35.
That will likely change to solely Rtools40 once R3.6 is released due to the
Msys system being built in to it.
There may be some library conflicts between Cygwin and
