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),
Target=r...

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 over to procmail. I
set up procmail's verbose logging feature for that user an...

Ajax.InPlaceEditor on Safari & Firefox
...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...
Could somebody on a Mac please confirm this behavior? I''m always
worried that I am not doing something right before I submit a bug
report.
All best,
Tench

A message, when moved by multiple clients with same account and same filters, can be duplicated by filters on destination imap folder.
I'm still collecting user feedback after moving from uw-imap to
dovecot development release 1.1.rc3.
What said in the subject seems the 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

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).
I fitted a model in which 'Machine' was a fixed effect and 'Worker'
was random (intercept), wh...

Question regarding analysis of normalised data
...in 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.
Gene expression is measured in triplicate, that is I have three values for
each measurement of each animal, and normalised to a standard gene.
My problem is, that there is no guarantee that one of the measurements of
either the gene in interest or the standard gene does not fail, so I need to
take the relative means of the triplicates, bu...

Index corruption causes child process to die
...y be caused by Tbird's message
filtering - I'm asking it to filter certain messages from INBOX to
subfolders.
When the error occurs, Tbird pops up an error message saying it can't
connect to the mail server, but I don't lose any messages it seems.
Instead, I get duplicates and even triplicates when I restart Tbird.
Any work around for this?

multiple ldap servers in bdc/pdc environment
...#39;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
entries in my smb.conf I get duplicate or triplicate users listed when
performing a /usr/local/samba/bin/pdbedit -L, and all 2 or 3 LDAP
servers get queried no matter what. Is there anyway to list multiple
backup LDAP servers instead of just having overlapping SAMs?
Also, there will be some remote offices connected via relatively
high-latency WAN li...

Scrubbing a zpool built on LUNs
I''m building a system with two Apple RAIDs attached. I have hardware RAID5 configured so no RAIDZ or RAIDZ2, just a basic zpool pointing at the four LUNs representing the four RAID controllers. For on-going maintenance, will a zpool scrub be of any benefit? From what I''ve read with this layer of abstration ZFS is only maintaining the metadata and not the actual data on the

Do *not* pass '...' to NextMethod() - it'll do it for you; missing documentation, a bug or just me?
Hi,
although I've done S3 dispatching for more than a decade now, I think
I managed to overlook/avoid the following pitfall when using
NextMethod():
If you explicitly pass argument '...' to NextMethod(), you will
effectively pass those argument twice to the "next" method!
EXAMPLE:
foo0 <- function(...) UseMethod("foo0");
foo1 <- function(...)

Best way to duplicate a live Centos 5 server?
...n shutdown the physical server and switch to the
virtual one.
But after getting iSCSI working... I realize I could not create a md
device on a mounted disk. Unfortunately this old C5 wasn't setup with
md raid 1 originally so I can't just add a the iSCSI target as an
additional member for a triplicate.
So I remembered DRBD was supposed to be used for replication.
But after getting things set up, running the drbd-admin create-md
command gave me this scary warning it will destroy data on the disk.
Apparently because drbd writes meta data to the drive. So that appears
to be a no go too.
Am I mis...

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,
