How to draw frequency domain plot with xts time series data
Hello,
I'd like to convert the below time-series data with fft or wavelet related function and plot it.
Could you let me know
1. How to convert xts data frame format to list format ?
2. How to plot fft or wavelet diagram ?
Here is the data :

Tukey post hoc comparison (glht?) after 3factorial mixed model (lmer)
Hello, dear R-community.
This is a question about TukeyHSD between factor combinations of a Three-Way
ANOVA, which is - since it is a multi measure ANOVA - not a simple ANOVA but
a Generalised Linear Mixed Model (GLMM), calculated with "lmer".

Bug#1042842: network interface names wrong in domU (>10 interfaces)
Package: xen-utils-4.17
Version: 4.17.1+2-gb773c48e36-1
Severity: important
Dear Maintainers,
On one of our domUs we discovered that the network interface names were
wrongly assigned since recreating the domU after an upgrade to bookworm.
If over 10 network interfaces are configured the mapping (dom0) vifX.10
<-> eth10 (domU) does not apply anymore.
Instead the interfaces on dom0 are

R-alpha: fitted = 0 of 1 in logistic regression
TASK: problem with "glm" with binomial errors
STATUS: Open

in glm(,binomial) it's possible that loss of significant
digits make expected values 0 or 1 even though there's no
divergence of the fit. (Happened to me with menarche data,
infants and grown-ups included)

Modifying a list: what gets copied?
Hi all,
In my continued effort to understand when and what R copies, I've
designed a small experiment to try and figure out what goes on when a
list gets copied - is it a shallow copy or a deep copy. I believe the
following experiment isolates the difference:
options(digits = 2)
powers <- 4:6
n <- setNames(10 ^ powers, paste0("e", powers))
xs <- lapply(n, seq_len)
zs <-

[LLVMdev] FYI: Phoronix GCC vs. LLVM-GCC benchmarks
I have run the john the ripper test.
I have used the official archive (same version as phoronix) from
http://www.openwall.com/john/g/john-1.7.3.1.tar.bz2
To build with llvm-gcc, replace the line CC = gcc with CC = llvm-gcc.
I have used the following command to build : make clean linux-x86-sse2
(seems to be the best on x86-32)
The makefile invocation is "gcc -c -Wall -O2 -fomit-frame-pointer

ctdb tcp kill: remaining connections
Hello,
we are using ctdb 4.15.5 on RHEL8 (Kernel 4.18.0-372.32.1.el8_6.x86_64) to provide NFS v3 (via tcp) to RHEL7/8 clients. Whenever an ip takeover happens most clients report something like this:
