What if my Windows AD Domain Controller Goes Down?
There are three DCs in my Windows 2003 AD domain, but I have noticed
that only one of them is referenced in my krb.conf and krb5.conf. Should
there be a reference to one or two of the other domain controllers? If
the DC goes down, how will my Samba/Winbind servers authenticate?

Long to wide format without time variable
Hi all,
I am trying to convert a data set of physician death codings (each individual's cause of death is coded by multiple physicians) from long to wide format, but the "reshape" function doesn't seem to work because it requires a "time" variable to identify the sequence among the repeated observations within individuals. My data set has no order, and different

[Possible spam] New project - any volunteers?
Greetings! (and apologies upfront for any duplication as a result of my cross-posting)
It''s been five weeks now since I began working with RoR. My experience has been incredibly positive. So much so that I''m emboldened to undertake a project I''d previously concluded I no longer had the technical chops to even _start_. I''ve included a brief description of

Selective Survival Statistics with R
Hello friends and fellow R users,
I have a problem to which I have been unable to find a solution: I am
gathering survival data on patients undergoing treatment with a new kind
of stent. I want to generate survival data and plot survival curves of
these patients based (among other things) on the treating physician. My
data set has been tabulated in the following manner:

Is R good for not-professional-statistician, un-mathematical clinical researchers?
Alternate title: How can I persuade my students that R is for them?
Alternate title: Can R replace SAS, SPSS or Stata for clinicians?
I am teaching introductory statistics to twelve physicians and two veterinarians
who have enrolled in a Mentored Clinical Research Training Program. My course is the
first in a sequence of three. We (the instructors of this sequence) chose to teach

mcmcglmm starting value example
Hi R-users:
Can anyone give an example of giving starting values for MCMCglmm?
I can't find any anywhere.
I have 1 random effect (physicians, and there are 50 of them)
and family="ordinal"?
How can I specify starting values for my fixed effects? It doesn't seem to have the option to do so.
Thanks, Ping

mcnemar.test odds ratios, CI, etc.
Does anyone know of another version of the Mcnemar test that provides:
1. Odds Ratios
2. 95% Confidence intervals of the Odds Ratios
3. Sample probability
4. 95% Confidence intervals of the sample probability
Obviously the Odds Ratios and Sample probabilities are easy to calculate
from the contingency table, but I would appreciate any help on how to
calculate the confidence

EMACS/ESS problems
Hello all,
since we're on the topic of R-editors. I am using emacs/ess on a unix
workstation (to interact with R and have been having a little problem. I
usually write the R commands I need to run in a separate buffer then
copy and paste them into the *R* buffer for evaluation. The problem is,
if any command is spread over multiple lines emacs/R hangs when I paste

R usage -- for article
Hello all,
I write a decision-support column for a computing magazine,
Intelligent Enterprise. In my next column, I'll be revisiting a topic I
wrote on 3 years ago, open-source analytical software. R is perhaps the
most successful open-source analytical package.
I'd like to hear from users, especially those who chose R for some
other reason than that it's free, about what

model-based clustering
Hello,
I was wondering whether a Poisson mixture modeler/cluster analysis
package is available for R. I scanned CRAN packages and couldn't find
anything but I thought I'd ask. If not could anyone recommend a non-R
open source package. I have found 'snob' but this program seems a bit
hard to use in an automated, non interactive fashion.
regards,

variance components
Please forgive the cross posting. I sent this to Medstats and have not received any response.
I am looking for a good written explanation of components of variance (a.k.a variance components), in particular as they are used in genetic analyses. Does anyone have a suggestion? I am interested in books, articles and on-line material. I intent to give the material to some of my students none of whom

Apple shares?
Hi,
I have a need to do some file transfers between my AIX 4.3.3 boxes and Apple
PC's. I use SAMBA to provide shares to PC's, but I know nothing about Apple.
FTP is an option, but less desirable than setting up a share. Does anyone
have experience with using SAMBA to set up shares with Apple clients?
I know that there are, other products to accomplish what I ask, but in terms

Selective blocking of password authentication
I'm running OpenSSH 3.4 and have the situation that some users want to
allow password authentication into their accounts and some explicitly
want to disallow password authentication. Is this possible? I wasn't
able to come up with a way looking through ssh_config and sshd_config,
as well as some FAQs.
It seems the problem is that there is no scoping of directives in sshd_config,

Clustering Question

My case has N physicians with each seeing M patients.
One physician could have seen a group of patients, or,
a patient could have been seen by multiple number of
physicians. In order words, there are overlaps. Now,
I have the following NxM matrix
Patient#1 Patient#2 Patient#3 .......
Patient#m
Physician#1 1 0 1 .......

For Loop Syntax
Hi there,
Just wondering if someone can help me with the correct syntax to use
with for loops?
I have split my original file by count, & wish to first of all assign
new tables based on the splits. Then I just want to create a new
variable. Please see code below.
This code works outside of a loop so I am just trying to code so I don't
have to repeat numerous times.

Hi,
Hm, the string inserts are different, too. Any encoding issues? Your
user name uses extended ASCII, too, right? Not sure if that''s
significant or not.
I''ve cc''d the win32utils-devel list to see if anyone has any ideas.
Thanks,
