Subsetting to unique values
I want to take the first row of each unique ID value from a data frame.
For instance
> ddTable <-
data.frame(Id=c(1,1,2,2),name=c("Paul","Joe","Bob","Larry"))
I want a dataset that is
Id Name
1 Paul
2 Bob
> unique(ddTable)
Will give me all 4 rows, and
> unique(ddTable$Id)
Will give me c(1,2), but not accompanied by the name column.

Working with temporal data
Hi,
I have several files with data in this format:
20070102
20070102
20070106
20070201
...
The data is sorted and each line represents a date (YYYYMMDD). I would
like to analyze this data using R. For instance, I would like to have
a histogram by year, month or day.
I've already made a simple Perl script that aggregates this data but I
believe that R can be much more powerful and easy on

Is FLAC fully cooked for OS X yet?
OK, so I've been trying for a day now to get FLAC implementation in
our apps. Suffice it to say that due to the "interesting"
documentation and the inability to compile this thing from the
source, I'm not sure we can do it yet. I am writing in to see if
there's anything I'm missing before I make the conclusion that we
have to wait...

UPS support on CentOS 4.4
I have an APC Back-UPS XS1500 powering my computer. It may be overkill
for a single computer but it makes me feel secure.
Gnome power management will not install on CentOS 4.4 because of
dependency problems.
I have installed the acpupsd daemon and this will protect me against
power failure but the GUI interface to it, gapcmon, will not install due
to dependency problems. I know that some

rspec_autotest no longer re-runs tests with rspec 0.7.5
Has anyone else encountered this problem?
What I mean is, rspec_autotest runs all specs, then waits. When you
change a spec, it reruns that spec. However, if that spec now passes,
it should run the whole suite again, so you can see the next one to
work on. It no longer does this. This renders it somewhat useless.
Does anyone have autotest working with rspec 0.7.5, or does anyone
have any

yet another faxing issue (outbound only, via ATA)
2 Asterisk servers 1.2.12.1
Connected via IAX2, same switch, GigE, no packet loss, etc
1 with a Sangoma A101 for a PRI to the PSTN
Ulaw
QoS enabled
NAT for the registered ATA boxes, no nat between the * servers
Faxing inbound:
Call from PRI hits the first Asterisk server
Then talks to the 2nd via IAX2
NVFaxDetect receives the fax, converts to PDF and emails it out
Works great!

Best Hardware for Asterisk Server?
Hey guys,
In your experience what is the best way to go for a production asterisk box
in your offices? With desktop prices so cheap you might think that you
should just buy them off the shelf, but is that really a reliable machine?
Anything you can tell me that would assist me in deciding the best way to
obtain and maintain these boxes would be very helpful. I have even looked
into building

(OT) Where to post free source for AGI?
Hey all,
After figuring out a problem with AGI and freepascal, I have finished
writing a small Cepstral (http://www.cepstral.com) AGI app. I wrote a
small readme for it at http://www.datatrakpos.com/misc/dial/readme.txt.
I'd like to give it to the community (source/binary) and was wondering
where to post it?
The wiki?
Also, anyone have suggestion on licensing? LGPL? FreeBSD?
Thanks

Freeze when swithing vt
Hello. I am running 0.3.6 compiz under Fedora Core 6 and nvidia 1.0-9631

and then back to x with ctrl-alt-f7 locks up the system with a black
screen more or less (sometimes the lockup is complete, sometimes the
cursor moves and it is possible to switch back to console), A user on

fastthread 0.6.1
I just realized -- if fastthread can be included while Mutex-using code
is already running, then the definition and replacement of the classes
needs to happen atomically. Otherwise, it creates a race condition
where a thread can e.g. end up seeing an incompletely defined Mutex
class or none at all.
fastthread 0.6.1 addresses this by defining the classes and then
atomically swapping the constant

Bug in update()? (PR#6902)
Dear all,
I noticed the following while playing around with fitting log-linear
models to contingency tables using R 1.8.1, but the problem also
exists under R 1.9.0.
A reproducible example uses the following contingency table:

> data(quine)
> tmp <- with(quine, expand.grid(Eth=levels(Eth), Sex=levels(Sex),
+ Lrn=levels(Lrn), Age=levels(Age)))

[LLVMdev] llvm-gcc4 mirror back online
Jeff,
The config.cpp hack worked for me as a temporary solution. Devang is
working on the permanent solution. Try applying this patch to your
gcc/config.gcc file, it might
just re-enable your build.

You can connect them either as "friends" or as "users/peers". I
generally recommend the user/peer method for connecting two servers
since it clearly delineates which codecs and contexts are allowed.
