The documentation for the arima function in the package stats has a slight error. It references: Ripley, B. D. (2002) Time series in R 1.5.0. R News, 2/1, 2–7. [1]http://www.r-project.org/doc/Rnews/Rnews_2002-1.pdf This should be: Ripley, B. D. (2002) Time series in R 1.5.0. R News, 2/2, 2–7.

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

I have a JPEG map of temperature data, coded using a given legend where blues are cooler and reds hotter. Is there any preexisting R magic or package which might let me recover the value of the scalar quantity so represented given the RGB values at each point in the picture? After processing, I'd also like to push the results back through the translate to get an RGB JPEG again. Thanks for

Dear List, We are using RHmm to cluster data through HMM. We would like to restrict the transition matrix of HMM, to get hierarchical connections between clusters. But, RHmm doesn't seem to support these restrictions. Can any one suggest a library to do that. Thanks, Kishor

I wondered if there were standard practices in CRAN for delivery of R source implementing functions in R packages. I has encountered a couple of packages where the gzipped version of source contains very little, primarily the Help files describing the functions in the package. In some cases I can find the source as the value of the function name. Given that these packages are released as GPL,

lm's "predict" function offers an "interval" parameter to choose between 'confidence' and 'prediction' bands. In the package "robust" and for "lmRob", there is also a "predict" but it lacks such a parameter, and the documented "type" parameter has only "response" offerred. Is there some way of obtaining

Apologies if this is the wrong place to ask. I'm not aware of a mail list devoted to database interfaces. Please direct me if so. I am trying to use TSMySQL. It loads RMySQL, and apparent the CRAN version has an .onLoad script which seeks out the local MySQL server. If that fails, the package fails to load. Thing is, I'm trying to access a MySQL database on a remote machine for which

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

Is it possible to export a list of installed packages from WinXP, and use that export to import the same set of packages on Ubuntu (Jaunty)? No doubt there is custom code that could be written, but I wonder if R 2.9.1 has anything built it to do that? Is it as simple as moving something like Rprofile.site from one machine to the other? I had a look at R-admin.pdf, and although it talks a lot

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?

Hi, I'm trying to fit a hidden Markov model (mixture of Gaussians) to stock prices (Open, High, Low, Close) data. Here's my code: #First download the data with package TTR library(TTR) n <- 200 data <- getYahooData("GOOG", strftime(as.POSIXlt(Sys.time() - n*24*3600),format="%Y%m%d")) keep <-

Recently, a package for convex optimization was announced for Python, based upon the LP solver GLPK, the SDP solver in DSDP5, and the LP and QP solvers in MOSEK. I'm aware GLPK is available for R, but wondered if anyone had good packages for convex optimization along these lines for R. TIA.

Can someone point me to the proper place in the documentation or on the Wiki where I can learn how to get R to stop interpreting the string "NA" as something special? I have a table in a database which contains (among other things) country codes and continent codes. The standard set of two-letter codes includes "NA" to denote "North America". I learned of the

Joyful. I'm adapting a FORTRAN 77 package for use with R. Pretty straightforward. Except for a glitch it took me some time to figure out. This existing package has subroutines which have parameters called "NA". So, I called subroutines like bnodes <- function(n, lst, lptr, lend, nodes, nb, na, nt) { ensure.all.numeric(list(n, lst, lptr, lend, nodes, nb, n.a, nt),

Hi, I need to draw hmm's in R.I also need to include a small plot near each state of the hmm.How can I do this? -- Rajesh.J [[alternative HTML version deleted]]

I am running a standard Centos 32-bit system on my home servers. I keep them up-to-date, but have not re-booted for several months. I see from /etc/centos-release that I am running 7.1. If I re-booted would

Dear Oscar,   Thanks for your help.It's so nice of you to explain this package to me.   Best Regards,   James LAN 发件人： Oscar Rueda [via R] <ml-node+s789695n4431468h14@n4.nabble.com> 收件人： monkeylan <lanjinchi@yahoo.com.cn> 发送日期： 2012年2月29日, 星期三, 下午 9:21 主题: Re: Bayesian Hidden Markov Models Dear James, The distances are normalized between zero and 1, so in your case all of

Hi, I went ahead and implemented something. However: - I cannot garantie it gives correct results since, unfortunately, the data used in Syrjala 1996 is not published along with the paper. To avoid mistakes, I started by coding things in a fast and simple way and then tried to optimize the code. At least all versions given the same results. - As expected, the test is still quite slow

To Whom It May Concern: I really admire the dedication and effort your group has. I am glad more and more people aren't buying into the Microsoft licensing schemes. Keep up the good work! I would like to add the server I have installed to our Active Directory Domain. We have one Win2003 PDC no subnets very basic stuff. I have read many chapters in the official how to guide and

There's Renka's STRIPACK, and TRIPACK, respectively, ACM TOMS Algorithms 772 and 751, and there's the R package "deldir" which does the Delaunay for a plane, but does anyone have or know of the tessellation in R for a sphere? Also, is there a standard indexing scheme for Delaunay facets, and perhaps of edges in such facets? I'd expect that to be a publication reference,
