names(dist(mat)) gives NULL in R 2.1.0
Dear list,
I do not know if this is a bug.
Let's suppose mat is a matrix derived from this code:
> x<-rnorm(10)
> y<-rnorm(10)
> names(x)<-LETTERS[1:10]
> names(y)<-LETTERS[1:10]
> mat<-cbind(x,y)
Now in R 2.0.1 I have:
> names(dist(mat))
"A" "B" "C" "D" "E" "F" "G" "H"

iraq statistics - OT
I came across this one:
http://www.nysun.com/article/32787
which says that the violent death rate in Iraq (which presumably
includes violent deaths from the war) is lower than the violent
death rate in major American cities.
Does anyone have any insights from statistics on how to
interpret this?

client-server setup for R
I am currently the only use-R at my company, but they are considering
buy a more powerful server and letting multiple people use it. They
asked me if R supports client-server setups. I know S+ has a server
version that does that. I didn't find anything about that on CRAN,
but hopefully someone can correct me.
I did see some stuff about R web servers

bilinear and non linear
Dear all,
there are R packages able to simulate or estimate bilinear model for time
series?
I know it is an open problem, but do exist something for very simplified
bilinear models?
Alternatively, what kinfd of non linear time series models are performed
in R?
If R is not able, could someone suggest me for some commercial softwares
to deal with bilinear models?

correlation in lme4
Dear all,
I have tried to consider a correlation structure in lme (package lme4), but
without success.
I have used something like:
> risul<-lme(y~x+ z , data=mydata, random=~ x | g, correlation = corAR1())
but the result is the same as:
> risul<-lme(y~x+ z , data=mydata, random=~ x | g).
Can anybody help me?

Is R a good choice for this?
Hi.
I'm working in a project about web-users behaviour analysis. In a few
words, it consists on:
- log-files recopilation and pre-analysis
- basic stadistics extraction (pages most visited, session lengths, etc.)
and on-line report generation in a web-viewable format
- more advanced analysis for web-users characterization
The purpose of my project is implementing my own data analysis, so

Web-application using R
Hi, all;
Our group is planning to develop a web-based analysis package with R. I
have some questions.
(1) Can we use R as a daemon-like way such that, after invoking R and
making it run in a kind of background mode, just put some R script into
R using some pipe-like mechanism and retrieve the result out of it?
(2) If this is possible, then how can we do it? If this is not
possible, then what

Monitoring qdisks and classes.
Are there any tools like iptraf or top to display tc stats? I would like
to see things like flowes(TCP or UDP connections) as well as simple per
second stats. I''m trying to monitor my p2p uploads and network
connections to see if things are getting into the right class.
I used to use mrtg for this, with some perl scripts I wrote. This project
of mine has long since bitrotten.

Problema con la lectura de datos
Otra opción es importar directamente los datos que necesites usando
XLConnect (sin llevarlos a CSV).
Ese paquete permite hacer cosas muy potentes desde el propio fichero de
Excel.
https://cran.r-project.org/web/packages/XLConnect/index.html
Recomiendo, encarecidamente, la lectura de sus dos vignettes.

Bandwith vsatl - not static
I have a existencial problem.
There are some provider that offer the service of bandwith asimetric as
download/upload link as for example 512/256. but most of them offer not
exclusive this amount of transmission or reception capacity. They usually
offer the service with more users as a ratio of 1/10.
How I can design a appropriate diagrama with htb where the amount of
bandwith could vary.?

save() size in XDR
Dear R-devel,
Is there a way to find the size in bytes of a save()
command --before-- the file has been saved?
If not, can anyone point me to some resources on XDR
so I can find a way to calculate it?
Thanks,
