A logit question?
Hello dear r-gurus!
I have a question about the logit-model. I think I have misunderstood
something and I'm trying to find a bug from my code or even better from my
head. Any help is appreciated.
The question is shortly: why I'm not having same coefficients from the
logit-regression when using a link-function and an explicite transformation
of the dependent. Below some details.
I'm

its plot with pch-argument
Hi mighty R-gurus and other enthusiastics,
I just encountered this:
library(its)
x <- its(sort(rnorm(10)), as.POSIXct(Sys.time() + 1:10))
plot(x, type = "p", pch = c(rep("A", 5), rep("B", 5)))
Am I missing something if I expect that all the points labeled as 'A' should be below all those labeled as 'B'?
Thanks,
Jussi M?kinen

Matrix to data.frame without factors
Hello and thank you dear R-people in advance.
This is quite basic question but which I have confronted occasionally and
get over it without satisfying solution. The question is about factors, this
time I would just like convert a data.frames NA-terms to 0 and get a
data.frame as a result. There might be a way to do that inside of the
data.frame but I think that it might be overcomplicated and

QR decomposition question
Hi all,
I wonder if this kind of questions are ok in this
list...
Quick question:
What does it mean than the rank of the QR
decomposition of a NxN matrix is N-1 ?
m: NxN matrix
qr(m)$rank equal to (N-1)
Long version:
I'm doing a manova on a matrix of 10 variables
and 16 observations.

glm link = logit, passing arguments
Hello R-users.
I haven't use R for a life time and this might be trivial - I hope you do
not mind.
I have a questions about arguments in the Glm-function. There seems to be
something that I cannot cope.
The basics are ok:
> y <- as.double(rnorm(20) > .5)
> logit.model <- glm(y ~ rnorm(20), family=binomial(link=logit), trace =
TRUE)

Mailman - searchable archive
Mailman works well for our mailing lists, but the archive is
unacceptable - the worst thing is lack of search function.
I got one tip for this:
1) emails converted to html format with mhonarc
2) search can be done with htdig
Opinions? Maybe there are better software solutions for this - I hope.

Installing 4.4 - problem on 386
I tried installing with several options (noacpi noapm; noprobe; noprobe
skipddc noacpi noapm nodma). Always I get the same error.
BUT this is not in fac a CentOS problem at all, because I get the same error
always when I boot from hd (Fedora Core), IF there is a CD in the CD-ROM
drive. (I tried with CentOS 1/4, CentOS 2/4 and a HP printer software CD.)
It must be something with the CD drive!

Disk quotas for Sendmail
Hi,
CentOS 5.x, Sendmail 8.13.8.
I would like to start using disk quotas on my Sendmail server, and optimally
they should be configurable by user or group. How can this be done? (I tried
to google, but no success.)

Openwebmail emergency (Perl)
After system update yesterday, Openwebmail now gives an error:
> Undefined subroutine &Compress::Zlib::memGzip called at /var/www/cgi-bin/openwebmail/shares/ow-shared.pl line 1175.
I tried to do
perl -MCPAN -e shell
install Compress::Zlib
But it says Compress::Zlib is up-to-date. What do to?? I cannot find an
answer by googling.

Where is my qemu command?
KVM virtualization is full of wonders. :-/
I would need to attach an USB disk to a vm, but how?

Hard disk, format, filesystem
Ok, I give up... I have to ask. This is CentOS 5.
I switched one of my raid1 disks, and I already thought I had succeeded. But
now it seems that something is very wrong with the first partition on the
new disk. Luckily my system is fully bootable with the other disk.
Here's some info. The new disk is sdb.

[OT] List of all email users
This is not CentOS-specific, hence OT.
I need a list of all email users on my system (there are hundreds of them).
The list could be extracted from /etc/aliases and the virtusertable.
Does anyone know of a script that would do this automatically? It would have
to
- exclude commented-out lines (of course)
- exclude duplicates
- produce a list of usernames (or maybe unresolved email addresses for

Old hd, new machine
What should I do to make an existing CentOS (5.4) disc boot up on a new
computer?
I just made on CentOS 5.3 installation on that machine, so I know the
hardware is compatible.
Would it be enough to boot with a DVD in rescue mode, or boot with
another hd, and install grub?

KVM resources?
Later this week I will have to install a serious KVM setup, and I am
looking for background material.
I found a nice how-to:
http://wiki.centos.org/HowTos/KVM
...but it is probably partly outdated by now.
Then there is a fine virtualization manual:
http://www.centos.org/docs/5/html/5.2/Virtualization/
...but it seems to be only for xen.
I plan to use either CentOS 5.6 or Scientific Linux

File sharing solution
I would like to offer my isp clients a solution for sharing (big) files,
basically on one-to-one basis. This is how I imagine it:
- an anonymous or registered user can upload a file
- on response (s)he will get a file-specific (or batch-specific)
username/password
- (s)he can send a link and un/pw by email
- the receiver can download the file
- the file will be automatically deleted from the

Migrating standalone systems to KVM
A while ago I got great instructions from Pasi for migrating standalone
systems to *xen*. However, now I have decided to use KVM instead, which
raises a new question:
How to migrate a standalone system to *KVM*?
I know a two-step way to do it:
standalone system -> xen pv guest
xen pv guest -> KVM pv guest
I read that xen -> KVM migration is trivially easy.
But is there an easier
