choice of an HMM package
We are trying to build a human respiration model.
Preliminary analysis of some breathing signals has shown that humans breathe
through switching among
a finite number of patterns.
Hidden Markov seems to be the right approach. Since most of our code is
written in R scripting language, finding an R package implementing an HMM
that we can use for our prototype would be very helpful.

Training parameters for a HMM
Hi,
I'm a newbie to the world of HMMs and HMMs in R. I've had a look at
the hmm package and the RHmm package but I couldn't see anything
straightforward on how a labelled sequential dataset with observed
values and underlying states might be used to construct and train a
HMM based on that data and no pre-computed values for the transition,
emission or initial state distributions. Does

help with package Rwave
I am looking for some explanations about the usage of the poorely documented R paclkage Rwave.
Has anyone ever tried out its functions for Wavelet Analysis ?
Thank you so much.

package "wmtsa": wavCWTPeaks error
I keep getting the following error when I look for minima in the series:
> aa.peak <- wavCWTPeaks (aa.tree)
Error in `row.names<-.data.frame`(`*tmp*`, value = c("1", "0")) :
invalid 'row.names' length
How can I work it around ?
Thank you.

How to enable R on-line search in HTML help
I use FireFox as my favourite web browser on my Mac OS/X 10.5
I double-checked that Java and Java scripts are enabled for FireFox. Nevertheless, I cannot use R on-line search help.
I called Apple Tech Assistance but they do not support FireFox. We tried to set Saphari as the favourite browser but
evidently R does not support it.
Does any one knw of a workaround this annoying problem ?

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.

Multivariate discrete HMMs
Hi r-help,
I have been using your RHmm package for some time and have recently
had to try using the package for a new dataset.
Basically I have a dataset with a number of discrete observation
variables that change over time, and I would love to try modeling them
using a HMM.
Basically I was wondering if RHmm can be used to model a multivariate
discrete HMM, i.e., the observations are a vector

Help with wavCWTPeaks
I cannot understand the following error printed out when I try to get the extrema of my time series.
I would appreciate some suggestion as I really cannot interpret the error. I might not be using a proper
set of parameters in calling such functions. I am learning by doing ...

Is there anyone in charge of package wmtsa ?
Here is another occurrence of wmTSA internal error.
My time series is a short breathing cycle (2425-Cyle_9.txt).
Since wmtsa functions that extract extrema seem to expect longer series than I have, I tried the folowing two tricks:
1) I prolong the 1-cycle series on both ends through duplicating the first value (on the left end( and the last value on the right end as any ties as the

How-To capture and handle errors with R
The following error occurs every now and then by calling a function of wmTSA package:
Error in `row.names<-.data.frame`(`*tmp*`, value = c("1", "0")) :
invalid 'row.names' length
I would greatly appreciate some guidelines about how to catch such an error upon its occurrence and have it handled by my own routine
rather than letting R stop the currently run

Unluckily a system upgrade patch messed up my monitor so I had to reinstall

I have R running back with text interface. I tried to get the nice R GUI up

a trous wavelet transform in R ?
There may be some chance that a proper wavelet transform may help me with signal features extraction.
I know R contains a number of packages implementing wavelett filters and/or transforms.
Is there an implementation of a trous wavelet transform ?

Bug#481105: [PATCH] adjust patch to pygrub and hvmloader
I just tripped over this issue with pygrub. The code is written such
that saying bootloader="pygrub" should cause the correct path to be
used, the attached patch simply fixes this path to be correct.
I don't have an HVM capable test machine handy (so I can't actually
confirm this works) but I think changing the default "kernel" for an HVM
guest to point to the correct
