How to Calculate the Mean by Multiple Groups in R
Hello,
I have a data frame with different groups (Time, Target, Conc) and
each entry has a triplicate value of the measurements OD and ODnorm.
How can I merge the triplicates into a single mean value?
I tried the following:
```
df = data.frame(Time=rep(1, 9), Well=paste("A", 1:9, sep=""),
OD=c(666, 815, 815, 702, 739, 795, 657, 705, 663),

Duplicate E-mail Problem
Hello all,
Definitely congrats on the 1.0.0 release!
Anyway, I'm having a problem, that may or may not be related to
Dovecot. Specifically, duplicate (and sometimes triplicate) emails are
appearing. These emails have exactly the same queue ID, so its not that
they were sent multiple times. These dup emails do not show up to me ever.
Postfix is being used as the SMTP, and it hands it

How to Calculate the Mean by Multiple Groups in R
Hi,
I think you're misunderstanding which set of variables go on either
side of the formula.
Is this what you're looking for?

Time Target Conc OD

2 1 BACT 2 745.3333

Ajax.InPlaceEditor on Safari & Firefox
Hi,
I''ve downloaded the latest svn trunk and was glad to see that
Ajax.InPlaceEditor forms can now be correctly submitted on Safari as
well, with the server response being correctly displayed as well.
The problem is, however, that clicking again on the same element
(after sumbitting it first) will duplicate the submit form. The next
attempt will triplicate it etc, etc...

Also,

Time Target Conc OD ODnorm

2 1 BACT 2 745.3333 88.33333

(You might wish for "cbind(OD,ODnorm) ~ . - Well", but aggregate.formula is not smart enough for that.)

A message, when moved by multiple clients with same account and same filters, can be duplicated by filters on destination imap folder.
...obvious result of an improper configuration.
Office emails are configured and accessed on multiple clients with the
same automatic filters, and sometimes the filtered emails get
duplicated on the destination folder.
The fact is that this was perfectly working with wu-imap (without any
duplication/triplication of emails).
I'm looking if there is some workaround to keep this client misuse
working with dovecot.
Could an email have a sort of "primary key" that forbids it's
duplication in the same imap folder?
Regards,
Diego.

linear mixed model question
Hello,
I wanted to fit a linear mixed model to a data that is similar in
terms of design to the 'Machines' data in 'nlme' package except that
each worker (with triplicates) only operates one machine. I created a
subset of observations from 'Machines' data such that it looks the
same as the data I wanted to fit the model with (see code below).

Question regarding analysis of normalised data
Dear all,
I want to see if the treatment of an animal with a specific compound has an
effect on the expression of certain genes. Though my question is based in
biology, it really is all about how to deal with the standard deviation in
normalised data.
I have three groups of animals; untreated, treated with placebo, and treated
with a single concentration of the compound in question.

multiple ldap servers in bdc/pdc environment

I'm setting up a number of samba DC's across several branch offices
using the Samba 3.0.0 release's native LDAP support. I'd like to build
some redundancy into my setup, such as having slave LDAP servers in case
the master is down/unavailable. However, when I have multiple ldapsam

## INCORRECT: Passing arguments '...' explicitly will *duplicated* them.

Best way to duplicate a live Centos 5 server?
I've got a CentOS 5 server that I want to migrate over into a
virtualized instance.
The problem is I need to minimize downtime so was trying to figure out
a way to "live" clone the original.
Initially, I thought I could do this via exporting an iSCSI target
from the virtual host, create a MD raid 1 array on the C5 server, wait
for it to sync, then shutdown the physical server and

DOS apps
Regarding WINE support for DOS apps:
Is there some fundamental reason why WINE could not be made to support
old DOS apps (like Warcraft), or is it just a matter of missing
libraries and such?
In other words, is there a reason why DosBox, etc. are full hardware
emulators, or why full DOS library support in WINE still wouldn't be
enough?
Thanks,
