depmixS4+transition
Dear helpers,
is there any possible that transition (in depmixS4) is in scale of two
variable, e.g transition=~scale(x1,x2)?
If it can be, how transition of two variable (covariate time) can be worked
in depmixS4-hidden markov model for time series.
Many thanks,
nglthu

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.
I have been

How to use depmix for HMM with intial parameters
Hello,
I have initial parameters for HMM model and I want to use depmixS4 package.
The parameters are in the form

ncol=3, byrow = TRUE)

depmixS4 prediction
I am getting started with using the depmixS4 package. First, I would like
to see I am very impressed with its speed and flexibility.
The question I have is regarding predicting on new data. I want to fit the
model on some sequences with observed responses, and then make predictions
on the right end of the sequences where the responses are not observed. I
see no prediction functionality anywhere,

depmixs4 standardError() issue
Hello,
I've been enjoying using the "Mixture and Hidden Markov Models in R" by Visser & Speekenbrink to learn how to apply these analyses to my own data using depmixS4.
I currently have a fitted 4-state mixture model with three emissions variables and one binomial covariate (HS). I am trying to compute confidence intervals using the following code, where fmms4s is the model:

Ordinal response model in depmixS4
I am running a latent class regression with 3 nominal and 2 ordinal variables using depmixS4 but the available response models do not include one for ordinal response. How do I go about this?

covariance matrix of model parameters
I am applying a hidden markov model on joint multivariate gaussian
distribution for 2 vectors. I am using the depmixS4 package in R.
Specifically, I am using the following code:
mod<-depmix(list(response = mom ~ mkt + p0 + p1, mkt~1), data = regvar,
nstates = 2,
family = list(gaussian(), gaussian()),instart = delta, trstart=Pi)
It seems that depmixS4 doesnt output the covariance estimates

Hysteresis modeling and simulation
Can anyone suggest a package or code for modeling a hysteresis process in R?
I'm currently modeling a certain dataset with a GAM using mgcv, something
like
gam(y~ s(x, by=z) + z, family = Gamma(link=log),data=data)
and getting fits with about 9 estimated degrees of freedom in the smooth for
each value of z. FWIW, z is a treatment applied to a system which should
have made an improvement,

contrib pkg install problem on Windows with R2.2.0
Dear R-helpers,
I made the package depmix for fitting hidden markov models.
After updating R to version 2.2.0 on my PC I got the following error when
installing the package from a local directory. One of the C files includes
the R.h file which apparently causes problems.
I call
R CMD INSTALL --docs="normal" depmix
and I get the following error:

Package for Clustering - Query
Dear R users,
Is there any package for Latent Class Analysis (to be used in a clustering
application) which supports mixed indicator variables (categorical and
continuous)?
Alternatively, is there any other clustering algorithm available that
supports this type of data?
Thanks in advance for your help.
Regards,
Lars.

Hidden Markov Models in R
R Community -
I am attempting to fit a model as described in Hampton, Bossaerts, and
O'doherty (J. Neuroscience) 2006. They use a bayesian hidden markov model
to model the Reversal Learning data. I have tried using HMM and depmixS4
with no success. My data is a Reversal Learning Task in which there are 3
sets of patterns over 3 blocks. The participant receives incorrect or

passing char to Fortran routine
Hello all,
I am using an existing Fortran routine that takes a single character string
as argument. The routine echoes the argument that I provide. When working on
OS X 3.9 there seems to be no problem, ie the Fortran routine nicely echoes
my argument. However, I compiled the same package on a PC (using all the
tools provided in the R for windows faq), and the routine only echoes the

Rsolnp examples
I'm interested in the Rsolnp package. For their primary function
"solnp", one example is given, and there is a reference to "unit
tests". Anyone know where these can be found? Also, Rsolnp is
used in a few other packages (e.g., depmixS4), but I cannot seem
to find source illustrating its call sequence, and the precise
definition of the functions passed.
Can anyone help?
