Kalman Filtering?
1. The function "KalmanLike" seems to change its inputs AND
PREVIOUSLY MADE copies of the inputs. Consider the following (using R
2.1.0 patched under Windows XP):
> Fig2.1 <- StructTS(x=Nile, type="level")
> unlist(Fig2.1$model0[2:3])
a P

strucchange Fstats() example
Dear all,
I'm trying to understand how the strucchange package is working and I have been looking at the examples given for the Fstats() function.
The first example (Nile), shows one peak in the F-stats and one breakpoint is estimated, that can be plotted using the following code
## Nile data with one breakpoint: the annual flows drop in 1898
## because the first Ashwan dam was built
data("Nile")
plot(Nile)
## test the null hypothesis that the annual flow...

R strucchange question -- robust regression
Is it possible to use some form of robust regression with the
breakpoints routine so that it is less sensitive to outliers?

Boxplot BUT with Mean, SD, Max & Min ?
People,
It appears that there is no way of getting Boxplots to plot using Mean,
SD, Max & Min - is there something else that would do what I want? I
couldn't find it . .
Thanks,
Phil.

predicting from a local regression and plotting in lattice
Hi R community,
I'm running R 2.7.2 on Windows XP SP2.
I'm trying to (1) plot loess lines for each of my groupings using the same
color for each group; (2) plot loess predicted values.
The first part is easy:
data1 <-
data.frame(Names=c(rep("Jon",9),rep("Karl",9)),Measurements=c(2,4,16,25,36,49,64,81,100,1,2,5,12,17,21,45,54,67),PlotAt=c(1:9,1:9))

The constant part of the log-likelihood in StructTS
Dear all,
I'd like to discuss about a possible bug in function StructTS of stats
package. It seems that the function returns wrong value of the
log-likelihood, as the added constant to the relevant part of the
log-likelihood is misspecified. Here is an simple example:
> data(Nile)
> fit <- StructTS(Nile, type = "level")
> fit$loglik
[1] -367.5194
When computing the log-likelihood with other packages such as KFAS and FKF,
the loglikelihood value is around -645.
For the local level model, the likelihood is defined by -0.5*n*log(2*pi) -
0.5*sum(log(F_t) +...

plot and lines with time series data
Dear all,
I am doing some time series analysis with R now. The problem is, when
I create a time series object using "ts" function, then after fitting
the model, the predicted values cannot be plotted with "ts" object
together using "lines". ie.
ts.series<-ts(x,start, end)
plot(ts.series)
lines(predict(fit.model))
This doesn't work.
Does anyone know about

Dial Plan Conf
Here I am expecting to be configured following scenario:
User calls : it will play a sound will ask for input DTMF, then call will be
given to particular extension for any DTMF entered.
But its not working as expected.

map_ptr warning
I am trying to finalize the use of rsync for updatiung a new nfs server
before we take the old one offline. I keep getting the following
warning during the rsync process:
Warning: unexpected rad size of 0 in map_ptr
Any ideas where this comes from and how to make it go away? I am using
rsync 2.5.2 on Solaris 8 to pull data from rsync 2.5.2 on Solaris 7.

Help with acf
I would like to get the result of acf min of lag 2 and max of lag 50.
When I use time series ( acf, lag.max = 50, type="covariance"), I
got lag 0 to lag 50. How do I get lag 2 to lag 50?
Sincerely,

brown, durbin , evans ( 1975 )
Does anyone know where
I can get R code for plotting
the Brown , Durbin
and Evans cumsum
procedure ( 1975 ) ?
I wrote my own code but
I am a little worried
that my confiodence bands
may not be correct ( I find the formula
in the original paper confusing and S+Finmetrics
has a formula but that formula implies that
there should be 4 lines as far as I can tell ) so
I would like to see someone

someone with a clue. Unfortuately, I lack clue wrt to wine development.
The program is available from http://www.aopa.org/flight_planner/
However, you need an AOPA account to login. I'm happy to run any tests

Parked Call
I have a question,
I am unclear on how to park a call. I know that you are supposed to be
able to press "#" and then transfer the call to extension 700. However,
* doesn't seem to be graping the dtmf. I am using dtmfmode=inband.
Asterisk is in the media path as well.
Thanks in advance

Sweave, beamer and alert within code chunks
Hi all,
Using Beamer, in order to highlight a piece of R code I do something
like this - note the "\structure" and "\alert" commands:
\begin{semiverbatim}
> mleOut <- \structure{dlmMLE}(Nile,
+ parm = c(0.2, 120), # initial values for optimizer
+ lower = c(1e-7, 0)) \alert<2>{# V must be positive}
> mleOut$convergence \alert<3>{# always check this!!!}

How can I get a similar effect using Sweave?
