Created a DVD from Gnome Desktop -CentOS-5.3
I am trying to put the dvd iso image of CentOS-5.4 onto a DVD. I
have an LG multi-writer installed. I have used this device on this
host to created CDs in the past but this is my first attempt at
creating a dvd.
When I put a blank DVD-R media in the drive then I see a desktop
icon for "CD-ROM Disc" created. When I open the bittorent folder
and click on the iso image

Beginner's Stumbling Blocks
Others have commented on the usefulness of adding an explicit list of what
should be included in the kernel. I second that.
There''s another thing that''s tripped me up: While iproute2 compiles and
installs easily (on a Red Hat 6.1 box), the documentation is in a format
that - while not obscure to old Unix hands - requires compilation, which
requires:

R-Latex question
Hi, maybe my question is not typical. I want to make R table-kind output to
be readable immediately in Latex but I am struggling with symbol '\' needed
for instance in '\hline'. For example when 'Table' is a matrix class object:
cat("&",Table[1,1], "&",Table[1,2], "\n");flush.console()
cat("\hline \n");flush.console()

tiny bug in R installation (redhat)
First, let me join the chorus of praise for R. (Hey, isn't somebody going
to analyse all these praise emails in some statistical way?)
I'm writing to point out an error in the file permissions in the
linux/redhat version. (I'm using R-base-1.0.0-1.i386.rpm, by the way.)
The permissions in /usr/lib/R/doc/html aren't correct, since

plot() with type="s" and lty=2 (PR#2630)
Full_Name: Jerome Asselin
Version: 1.6.2
OS: RedHat Linux 7.2
Submission from: (NULL) (142.103.173.179)
In the following example, the line type lty=2 does not show properly
across the entire line.
x <- c(seq(0,.5,.001),seq(.6,1,.1))
y <- rep(1,length(x))
plot(x,y,type="s",lty=2)

tapply and names
I have a data frame containing children, with variables 'year' = birth
year, and 'm.id' = mother's id number. Let's assume that all the births of
each mother is represented in the data frame.
Now I want to create a subset of this data frame containing all children,
whose mother's first birth was in the year 1816 or later. This seems to
work:

survreg: fitting different location parameters
Hi R-Help!
My question: I have lifetime/failure data of machines with different
stress levels and i think an weibull/extreme value distribution would
fit this data. So I did:
model1 <- survreg(Surv(lfailure)~stress,data=steel,dist="extreme")
(where lfailure=log(failure))
Now I would like to do a likelihood ratio test to test the hypothesis

Error in the inverse of a diagonal matrix?
I?m new to R so maybe this issue has been asked before and I still could not read the complete set of past messages sent to the list.
I found a weird behabiour that I will explain with a simple example. Lets consider the following block of commands:
> x <- diag(c(1,4,10))
> x
[,1] [,2] [,3]
[1,] 1 0 0
[2,] 0 4 0

interpreting Weibull survival regression
Hi,
I was wondering if someone can help me
interpret the results of running
weibreg.
I run the following and get the
following R output.
> weibreg(Surv(time, censor)~covar)
fit$fail = 0
Call:
weibreg(formula = Surv(time,
censor)~covar)

read.spss: unrecognized record type
When reading an spss file, I get the following message:
Warning message:
../totmorH.sav: Unrecognized record type 7, subtype 13 encountered in system file.
What does it mean? Do I have to worry? The result looks as expected. I do
not have (easy) access to SPSS, so I cannot check exactly that I got what I
should have.
Thanks,

And, I'm using R-2.0.1 on Debian testing (from source).

Books on survival analysis and R/S
I will be giving a course in survival analysis using R (of course!) for
people who know nothing about the subject (including R), but know basic
statistics. I'm looking for a suitable course book. Therneau & Grambsch
(2000) is an excellent book, but too much for this course. I need somthing
more elementary.
I have a vague memory saying that such books exist, but I cannot find any

Two names of a function
Is it possible to let a function be known under two names without having
two identical copies of the function body?

TeX distribution on Windows
I'm looking for a Windows distribution of TeX that works with R, after a
few years' absence from Windows. On Duncan Murdoch's Rtools page fptex is
still recommended, but it turns out that fptex is "defunct" as of May 2005,

Pointer to covariates?
In the first line, use the dist function, found in library mva,
to get the distance between each pair of rows. From this
calculate an incidence matrix for which element i,j is true if
row i in dat equals row j in dat (and false elsewhere).
In the second line, for each row calculate the indices of
the matching rows and take the minimum of those as the key.

[PATCH] virtio-balloon: fix managed page counts when migrating pages between zones
In case we have to migrate a ballon page to a newpage of another zone, the
managed page count of both zones is wrong. Paired with memory offlining
(which will adjust the managed page count), we can trigger kernel crashes
and all kinds of different symptoms.
One way to reproduce:
1. Start a QEMU guest with 4GB, no NUMA
2. Hotplug a 1GB DIMM and only the memory to ZONE_NORMAL
3. Inflate the balloon

Plotting female and male signs
Dear R-users,
Just like other users (as seen from previous posts on the list), I would
like to use female and male signs in plots. I found B. Ripley's post
about using Unicode characters. However, it doesn't works for me.

ASMTP setup on 4.8
Hello,
I'm trying to set up a sendmail server on 4.8 that supports auth-based
relaying. I followed the procedures at

having to run makes manually in the library directories, I had no
difficulty. I did not use the rebuild world recommendation, though.
Everything is up and running, but whenever I try to send mail
