Using ksmooth to produce the resulting plots
Hi,
Consider the Nottingham temperature and the Sunspot data:
>data(nottem)
>data(sunspot)
Assume that we may model each data set by a nonparametic autoregressice
model of the form
Yt = m(Yt-1) +et,
What are the value of x and y for using function
ksmooth(x,y,"normal",bandwidth=0.01)?
Thanks a lot!

Preliminary version of ts package
There is now a preliminary version of a time series package in the R-devel
snapshots, and we would welcome feedback on it. It is based in part on the
packages bats (Martyn Plummer) and tseries (Adrian Trapletti) and in part
on code I had or have written. (Thanks for the contributions, Martyn and
Adrian!) Some of the existing ts code has been changed, for example to plot
multiple time series, so

(no subject)
can you recommend a good manual for R that starts with a data set and gives
demonstrations on what can be done using R? I downloadedR Langauage
definition and An introduction to R but haven't found them overly useful.
I'd really like to be able to follow some tutorials using a dataset or many
datasets. The datasets I have available on R are

sunspot data in R 2.0.0
I noticed this in the NEWS:
o Datasets 'sunspot.month' and 'sunspot.year' are available
separately but not via data(sunspot) (which is used by package
lattice to retrieve a dataset 'sunspot').
Now, the 'sunspot' dataset included in lattice was actually a mistake, I
realized later that I instead wanted the 'sunspots' data from

Questions for package ts prediction
Dear helpers,
I am trying to write a function to return prediction values using
package ts. I have written three different versions since I am not sure
what's wrong with my func2. func and func1 return the same results.But
func1 and func2 don't. In particular, the only difference between
"func1" and "func2" is the function variable name being y and data,
respectively.

use ts objects within the "seas" package for seasonal stats ; to compare years with each other for change detection
Hi all,
Does anyone know how ts objects ts(base) can be used within the 'seas'
package? I would like to obtain seasonal statistics of regular
time-series and for example look at the result of the plot.seas.var()
function or use the change function() to look at change between periods
or time-series.
The nottem time-series are similar to the time-series we are analyzing

unable to add IP address to eth0:0 eth0:1 etc
Hi all,
I need to (quickly!grrr) update IP addresses for which a given machine
will answer.
I did this:

SELinux questions, upon restarting BIND
Hi all,
On my newly up-and-running nameserver (CentOS 5), I noticed the
following alerts in /var/log/messages after restarting BIND. (lines
inserted to aid in reading).
As I'm new to SELinux, I'm hoping for some pointers on 1) if this is an
issue which simply *must* be addressed, or if it's something I should
live with, and 2) how to eliminate the warming messages without
sacrificing

lattice: formatting tickmark labels of log scaled axes
Problem:
How can I format tickmark labels of log scaled axes of lattice
graphics in the usual `xxx'-Format (and not in the scientific
format).
Example:
(according to the help-page of xyplot):
In the first plot I get the xxx-Format,
in the second plot I get the scientific format (10^xxx):
data(sunspot)
plot( 1:37, sunspot, log='y',type='l')
xyplot( sunspot ~ 1:37,

stl in library(ts)
I am running R 1.2.2 under Linux. When using the function stl in
the ts library, how can I save the seasonal component? What I
would like was something like:
library(ts)
data(nottem)
data.stl <- stl(nottem, "per")
x <- data.stl$sea
This what I get:
> x
NULL
I would, however, like to store in x the seasonal component.
Thanks in advance. Francisco.

New CentOS DNS Server woes
Hi folks,
I've put my new DNS server in place, told the primary that this IP would
be pulling zones and restarted BIND on the primary.
I configured my named.conf file to pull zones from the primary, started
BIND on the new box. Here's where I get confused

R-alpha: Logarithmic scales
Here are another three problems with logarithmic scales:
1) segments() does not work with logarithmic scales. I suggest to change
lines 962-973 in "plot.c":
for (i = 0; i < n; i++) {
if (FINITE(xt(x0[i%nx0])) && FINITE(yt(y0[i%ny0]))
&& FINITE(xt(x1[i%nx1])) && FINITE(yt(y1[i%ny1]))) {
GP->col = INTEGER(col)[i % ncol];

R-alpha: various graphics Q.
"contour" can't return a list of contours (it would be nice)
"arrows" has different options from S-PLUS (no "open" or "rel" options,
no "lwd" parameter or graphics parameter pass-through; "size" in S
corresponds to "length" in R). [I know we needn't follow S-PLUS syntax
slavishly, but it would be nice at least to

cointegrating regression
Hi all,
Can I run a cointegrating regression, for example
delta Xt=a1(Yt-1-cXt-1)+E1t
and
delta Yt=-b1(Yt-1-cXt-1)+E2t
with R were
Xt and Yt are non stationary time series at t
a,b,c are parameters and E1t and E2t are error terms at t.
Yt-Xt is stationary
Any suggestions are welcome.
Best regards,

VARMA
Hi all,
I want to estimate parameters from a VARMA(p,q)-Modell.
The equations of the model or the model structures is given by:
Xt=beta1+beta2*Xt-1+beta3*Yt-1+epsilon1
Yt=beta4+beta5*Yt-1+espilon2
epsilon1 and espilon2 are white noise.
Xt is given by a vector of n elements e.g. (2, 4, 7, 9, …,n)’ and Yt is
given by a vector of n elements e.g. (4,9,12,17,…,n)’.

s.window in stl()
Hi,
This is actually a theory question.
I'm a bit confused by the s.window parameter in the stl() function (which
is in the ts package). For example, in the stl documentation it uses the
nottem data, and then:
plot(stl(nottem, s.win = 4, t.win = 50, t.jump = 1))
What does it mean by s.win = 4? Is it because a year has 4 seasons
(namely Spring, Summer, Autumn and Winter)? If so will it
