Partial Cross Correlation
Does anyone know of any R code for computing partial cross-correlation? I have examples of cross correlation functions (ccfs) that are not smooth but rather consist of a peak of several high values in consecutive lags, with sharp drops on either side. This indicates that y(t) is a function of some average of x(t-tau) at the set of lags tau over which the ccf is high. I could sort out these

PRI got event: HDLC Abort (6) on Primary D-channel of span 1
I receive this error on the asterisk console and it is pretty much
ALWAYS coming up.
Sometimes there will be a break where it does not display.
We had our PRI provider test the lines and they claim that there is no
signalling problem.
It doesn't matter if there are no calls or if there are 10 calls in
progress the error is still displayed.
I also get an annoying popping or clicking sound

Multiple time series and their names
Suppose I have multiple time series with names for each one, for example,
x <- ts(matrix(rnorm(30,0,1),10,3), names=c("Juan", "Tuey", "Trey"),
frequency=4)
So now, as I start to explore these series, if I do everything at once, the
names
stay attached to the series. For example,
plot(x) # gives a plot of the series with their names
acf(x) # gives the ACFs &

Without -O2 the error message goes away.

plot bg color in Mac OSX
Hi,
I am running R on my iBook (OS X 10.4) and whenever I try and plot a
model that has been run, I get a grey background. This makes the plot
difficult to read on b&w printouts. I have tried changing the background to
white (or any other color) without any success. Here's a current example
plot(augPred(m2corn.nlme, level=0:1), bg="transparent", lty=c(1,4), pch=19,

aov output question
Hello,
I currently get anova results out of the aov function (see below) I use the model.tables and I believe it gives me back the model parameters of the fit (betas), however I don't see the intercept (beta_0) and don't understand what the "rep" output means and there is no description in the documentation.
Another question: is there a function that outputs the results in a

Difference between arima(1, 1, 1) of y and arima(1, 0, 1) of diff(y)
Dear all,
When I run an arima(1,1,1) on an I(1) variable, y, I get different estimates to when I first difference the variable myself, e.g y2<-diff(y), and then run arima(1,0,1) on y2. Shouldn't these two approaches give the same output?
Any help will be much appreciated.

Problems with ARIMA models?
Dear R,
I have find a website where they report problem with ARIMA models in R. I
run the examples there and they give result as shown on the website. Does
this mean that nothing has corrected in R? Maybe you not have seen the
page, but the author said he contacted you.
Here is the URL: http://www.stat.pitt.edu/stoffer/tsa2/Rissues.htm
I like to know your opinion.
Mvh.

PRI got event: HDLC Abort (6) on Primary, D-channel of span 1
I also experienced this problem and the first thing that really helped out was changing the timing in the span line of the zaptel.conf. Change it to look like this (see below) and see if it helps out. I got the error much less after doing this and eventually got rid of the error completely by removing my raid drives, installing an IDE drive, enabling DMA mode on the Hard Drive, enabling APCI in

Time Series - ARIMA differencing problem
Hi,
I have been using this website (

models to my data. At the moment I have two possible methods to use.
Method 1
If I use
arima(ts.data, order=c(1,2,0), xreg=1:length(ts.data))
then the wrong value for the intercept/mean is given (checked on SPSS and

Security help desperately needed
I need to have the following services from my server:
imap - mostly by lan, but occasionally external

samba access - read and write to some directories
The problems I'm seeing are inconsistent, making it difficult to know how to
find the source. Samba access is essential to me. I use a server-based
korganizer, and without samba it's inaccessible. Sometimes it is

[LLVMdev] use of undeclared identifier '__NR_*' error while building clang

I am following this[1] tutorial to install clang. However, I have made a

I am getting the errors (given at the end) related to *undeclared

Port 32230 anyone?
Greetings,
Yet another strange pattern of traffic is being halted at the shorewall
firewall, but I have no idea what this is. IANA shows the ports
unassigned, and a net search yields only some of the same questions -
what is this port?
There are two machines as SOURCE, on the same class C network, adjacent,
even, sending one connect attempt to TCP port 32230 every five minutes.

[LLVMdev] Getting LLVM bit-code for programs using a couple of libraries
Hi guys,
I am compiling some programs with clang which use a couple of
libraries. When I compile with the command - "clang -O2 -I. -o hello
-ldl -llttng-ust hello.c tp.c", it goes successful.
My aim is to get the bitcode for these programs but if I try to
generate the bitcode with -emit-llvm option, it produces linking

[LLVMdev] LLVM IR on different platforms
Hi,
I am curious to know about LLVM IR as platform independent feature.
I have compiler some C and C++ applications that compiled on Linux 64bit

1) Will this execute without any issues?
2) Do I pass any option for making it operating system portable?
3) Can I generate bit code file also on Linux machine and then run on
