might the problem be in (double back slashes rather than forward slashes)

building recommended packages on Windows
Hi,
I am building 2.1.0 (re-release version, if that matters) on a Windows XP
machine. Following the instructions 3.1 "Building from source" in
R-admin.html, I managed to get up to 3.1.6. But when I try to build the
recommended packages, I get

help(arima) return value typo?
in ?arima (R-1.9.1), the return value component 'convergence' should be
'code'?
(it's a pity there is no reliable way to check return value documentation
consistency with the code, or is there?)

se.fit from predict.lm
hi,
i noticed that se.fit from predict.lm is the same whether interval="conf"
or interval="pred". it is not clear to me from ?predict.lm whether this is
intended or not. i suggest that se.fit should match the type of interval
requested, if interval is specified. suggested change in lm.R line 700
if(se.fit || interval != "none") se <- sqrt(ip)

Values greater than 1 or lower than -1 in ARMAacf
Dear all,
I need to compute the ACF (autocorrel) of an AR6 process, given the values
of its parameters (w1,w2,w3,w4,w5,w6).
First, I notice that there is an error as soon as the sum of the wi equals 1
:
"Error in drop(.Call("La_dgesv", a, as.matrix(b), tol, PACKAGE = "base")) :

Changing fonts of axis labels in Histogram() function
Dear All
I am using the histogram() function to plot two subsets from my data on the
same output display, i.e. there are two histogram plots
My code is:

xlab = "Age (years)",
strip = FALSE, strip.left = TRUE, col = "black",
border = "white", cex.axis = 1.1, family = "serif", cex.lab =

Bad Request
I have a repeated error in the asterisk console.
Incoming call: Got SIP response 400 "Bad Request" back from 10.0.2.136
It is repeated every few seconds and never stops until I restart
Asterisk.
It starts after I make a call to a certain extension, 202 which
transfers the call to another extension all phones then hang up.

stationarity tests
How can I make sure the residual signal, after subtracting the trend extracted through some technique, is actually trend-free ?
I would greatly appreciate any suggestion about some Stationarity tests.
I'd like to make sure I have got the difference between ACF and PACF right.
In the following I am citing some definitions. I would appreciate your thoughts.

pacf lags
pacf in devel seems by default to return a different number of lags
than 1.7.1 for $pacf. I don't see any mention of this in the NEWS file,
or any change in the documentation, so I suspect it is and error,
though it may be an undocumented improvement.
(Newbie question: How is the simplest way to display a function like
pacf.default that is not exported from a namespace?)

Still more auth problems
Firstly can I ask when the documentation site will be online again? I'm
struggling here without it.
Further to my recent post I have tried to simplify things a little.
I have used a VoiceXML app to simple call an asterisk extension. EG:
<form id="transfer">
<block>
<call name="xfer" dest="sip:101 at 10.0.4.147:5060"/>

pacf
Dear list,
according to the documentation of acf{ts}
"the partial correlation coefficient is estimated by fitting
autoregressive models of successively higher orders up to lag.max. "
However, R seems to return the Yule-Walker estimates of the PACF by
default. You can check this using c(1:10) as the series: the YW
estimates are 0.7000000 and -0.1527035 for lags 1 and 2 . If the PACF

Inverse autocorrelation fonction
I've been looking for an IACF() procedure in R for a long time (it's a very
convenient function to check for overdifferencing time series), and
eventually decided to write my own function. Here's what I came up with :

Plots spanning columns
Hi! I want to plot three graphs (residuals, ACF and PACF of a
model). Ideally I would use a c(2,2) disposition where the residuals
plot would start at position 1,1 and span to position 1,2. Then I would
plot the ACF in position 2,1 and the PACF in position 2,2. Maybe is
clearer like this:

partial correlation function for multivariate time series
Dear all,
I found the following behaviour with pacf() in the multivariate case,

x <- rnorm(1000,sd=10000)
y <- rnorm(1000,sd=1)
pacf(ts(cbind(x,y)),plot=FALSE,lag.max=10)

How to Label Certain Lags for a PACF Graph
When I use the command for PACF, lags 5, 10, 15, and 20 are labeled. I would
like to label lag 1. I would greatly appreciate if someone could tell me how
to do this. Below is the command that I am using:

Relaying calls to another SIP extension
Hi,
I am learning Asterisk for a small project.
At this stage I have an AsteriskNOW system running locally. I can call
SIP phone to SIP phone fine, the operator and voice mail work fine,
except some stuttering (probably caused by it running in MS-VPC)
What I need to figure out is...
I have an automated response telephony server (Voice Media Server)
available via a SIP URI like:
