Ashlee Vance's article on R in the New York Times
Ashlee Vance's article on R in the New York Times.
This is typical of the New York Times. Because they get to coast on the
prestige and reputation of their brand , they have a history of just this
sort of journalistic sloppiness. Whether it's the author or the editor at
fault doesn't really matter, they do this screw-up all the time.
Look, if you write an article on the first page of

Why is the R mailing list so hard to figure out?
Why does the R mailing list need such an unusual and customized user interface?
Last January, I figured out how to read Usenet mailing lists ( or
Usenet groups ) and they all pretty much work the same, learn to use
one, you've learned to use them all ( gnu.misc.discuss ,
comp.lang.lisp , and so on ).
What's the best way to view and read discussions in this group for
recent days? Can I

Tools For Preparing Data For Analysis
As noted on the R-project web site itself ( www.r-project.org ->
Manuals -> R Data Import/Export ), it can be cumbersome to prepare
messy and dirty data for analysis with the R tool itself. I've also
seen at least one S programming book (one of the yellow Springer ones)
that says, more briefly, the same thing.
The R Data Import/Export page recommends examples using SAS, Perl,
Python, and

How would you program an Adverse Events statistical table using R code?
A graph != A table.
I'm talking about a page full of summary statistics and advanced
statistics, with lots of cross categories on the top and left margin
of the table, as opposed to a visual display with x-axis and y-axis,
which is totally different.
(An example of how this is done in another language is available at
http://fivetimesfaster.blogspot.com )
For an AE table, you have an N and %

How do you do an e-mail post that is within an ongoing thread?
That may sound like a stupid question, but if it confuses me, I'm sure
it confuses others as well. I've tried to find that information on the
R mail-group info pages, can't seem to find it. Is it something
obvious?
To begin a brand new discussion, you do your post as an e-mail sent to
r-help at stat.math.ethz.ch .
As I am doing right now.

Difficulties With Posting To Ongoing Threads on the R Mailing List
A number of people are having the same problem as me, when you post as
a response to an ongoing thread, in place of your message, the
following message appears:
An embedded & charset-unspecified text was scrubbed ...
and a link is given that leads to the desired message.
It's better than nothing , but it sure is annoying, and some readers
will skip it instead of doing the extra link.

Awk and Vilno
In clinical trial data preparation and many other data situations, the
statistical programmer needs to merge and re-merge multiple input
files countless times. A syntax for merging files that is clear and
concise is very important for the statistical programmer's
productivity.
Here is how Vilno does it:
inlist dataset1 dataset2 dataset3 ;
joinby variable1 variable2 where ( var3<=var4 ) ;

[Patch] credit: Update other parameters when setting tslice_ms
From: Nate Studer <nate.studer@dornerworks.com>
Add a utility function to update the rest of the timeslice
accounting fields when updating the timeslice of the
credit scheduler, so that capped CPUs behave correctly.
Before this patch changing the timeslice to a value higher
than the default would result in a domain not utilizing
its full capacity and changing the timeslice to a value

Tripp-Lite SMART1500LCD: powers off with /etc/killpower...then powers back on...
Hi Everyone,
I recently bought a Tripp-Lite SMART1500LCD for my Linux Mint 19.3 machine,
connected via a USB cable. I installed Nut 2.7.4 from the Mint package
repository via sudo apt update && sudo apt install nut. Everything works
great: NUT issues low battery warning when it reaches the set low
battery point and then issues shutdown commands...computer shuts
down..then the UPS shuts

A really simple data manipulation example
In response to those who asked for a better explanation of what the
Vilno software does, here's a simple example that gives some idea of
what it does.
LABRESULTS is a dataset with multiple rows per patient , with lab
sodium measurements. It has columns: PATIENT_ID, VISIT_NUM, and
SODIUM.
DEMO is a dataset with one row per patient, with demographic data.
It has columns: PATIENT_ID, GENDER.

Compiling for Windows
Hello OpenSSH devs,
I'm hoping this is the proper forum for this question, but if not maybe some kind soul could point me in the right direction.
I've been tasked with maintaing a Windows application that currently, or will need to, make use of the following tools:

? ssh
? sshd
? sftp
I know there are a few packages out there already CopSSH being one of them (which does

problem using rJava with parallel::mclapply
Dear all,
I got an issue trying to parse excel files in parallel using XLConnect, the
process hangs forever.
Martin Studer, the maintainer of XLConnect kindly investigated the issue,
identified rJava as a possible cause of the problem:
This does not work (hangs):

Data cleaning & Data preparation, what do R users want?
R has a very wide audience, clinical research, astronomy, psychology, and
so on and so on.
I would consider data analysis work to be three stages: data preparation,
statistical analysis, and producing the report.
This regards the process of getting the data ready for analysis and
reporting, sometimes called "data cleaning" or "data munging" or "data
wrangling".
So as

[LLVMdev] LLVM MinGW binaries on Vista issue

Updated version attached with all your feedback, and others, hopefully fixed.
No applogies needed, attention to the details is always great. How often does documentation get the short shrift that we would never think of giving to code ;)

Problems with app_realtime
It seems that when setting qualify = 200 or qualify = yes in the database for
a sip friend/peer, RealTime does not update the registration status like it
should.
I also have several peers which have been offline and Asterisk still reports
them as registered, even though the registration seconds are only 200.
