Dear All, A new task view "ChemPhys" on chemometrics and computational physics is available on CRAN (http://cran.r-project.org/web/views/ChemPhys.html). It describes packages and functions that are of use in modeling chemical/physical systems. Suggestions and comments regarding this task view are welcome. If you think a new category, package or function should be added, please mail.

Dear List, Regarding the task views: I was wondering if it would be possible to replace the MedicalImaging task view with an ImageProcessing task view? Alternatively, a separate task view could be created. However, I suspect that there would be considerable overlap. In my opinion, a single task view for image processing, would be preferable. Also, I note that the Spatial task view contains a

I checked the R procedure HCLUST (hierarchical clustering) but it looks like it requires a full triangular n x n similarity matrix as input, where n = number of observations. The number of variables is 200. My data set has n = 50,000 observations (keywords), and I use ad-hoc similarity measures, not available in R, to measure keyword similarity. Here, the vast majority of the n x n similarities

The first release of "RNiftyReg", an R package for registration (alignment and resampling) of medical images, is now available on CRAN [1]. It may also be useful for other 3D array-like data sets. RNiftyReg is built on top of the NiftyReg library [2], and is written in a mixture of C, C++ and R. It currently supports 3D rigid-body and affine registration, and support for 2D and nonlinear

Have you checked here: https://cran.r-project.org/web/views/NaturalLanguageProcessing.html Speech to text is a very complex, specialized task requiring, I would expect, a lot of IP. It would not surprise me if you have to resort to big time, specialized software products with or without R. "Speech to text with R" found some hits, but mostly the google package you refer to. You might do

Hi, I sent the following e-mail to kexec-mailing list (kexec@lists.infradead.org) since subjects of makedumpfile are discussed on the mailing list. I want to inform this to xen developers since I think this function is useful for xen developers. Thanks. Itsuro Oda (see https://sourceforge.net/projects/makedumpfile/ about makedumpfile command.)

Problem on flexmix when trying to apply signature developed in one model to a new sample. Dear R Users, R Core Team, I have a problem when trying to know the classification of the tested cases using two variables with the function of flexmix: After importing the database and creating a matrix: BM<-cbind(Data$var1,Data$var2) I see that the best model has 2 groups and use: ex2

In general, statistical methodology queries, which seems to be your concern, are offtopic here.This list is about R programming. Consider stats.stackexchange.com for statistical queries. However, the CRAN task view on natural language processing might be useful, so you may wish to check it: https://cran.r-project.org/web/views/NaturalLanguageProcessing.html Cheers, Bert Bert Gunter

This question teeters on the brink of general statistics rather than an R-specific issue, but I'm hoping it boils down to how I coded V&R's EM algorithm for finite mixture modeling and not something worse (i.e. that my plan is impossible). Briefly, I'm trying to simulate an experiment where the hypothesis concerns bimodal vs. unimodal distributions, in order to see what

Hola: Me gustaría que me recomendarais paquetes o alguna forma de "hincarle el diente" para empezar a investigar en la siguiente cuestión. El proyecto trata de que, a partir de un numero grande de documentos pdf que contienen, básicamente, Notas Simples del Registro de la Propiedad deseamos extraer para cada uno de esos documentos una serie de ítems de información, a saber: -Finca

Hi, I work with remote sensing in Brazil. I would like to know if there is any algorithm or package that does image segmentation by region growing in R. Thanks, Eder. [[alternative HTML version deleted]]

Hi, I am traying to implement an STAR model, but I have some problems. I am following the instruction of the model, that they are in: http://bm2.genes.nig.ac.jp/RGM2/R_current/library/tsDyn/man/star.html that they are from: http://bm2.genes.nig.ac.jp/RGM2/pkg.php?p=tsDyn The model is: star(x, m=2, noRegimes, d = 1, steps = d, series, rob = FALSE, mTh, thDelay, thVar, sig=0.05, trace=TRUE,

Hello dear R-help group (and David Smith from REvolution), I would like to perform parallel computing using R with Condor (hopefully using foreach or other recommended solutions, if available) for some "Embarrassingly parallel" problem. I will start by listing what I found so far, and then go on asking for help. So far I found the a manual by Xianhong Xie from Rnews_2005-2 (see page

Hi, I'm interested in experimental design and data analysis on mixtures, like cake recipes where the sum of the components is fixed; e.g. <http://www.itl.nist.gov/div898/handbook/pri/section5/pri54.htm>. I can't believe that R doesn't have facilities to design and analyse such experiments, but I haven't been able to find them (I have looked quite hard!). Can anyone point

Good Morning, I am trying to create a new column of character strings based on the first two letters in a string in another column. I believe that I need to use some combination of ifelse and grep but I am not totally sure how to combine them. I am not totally sure why the command below isn't working. Obviously it isn't finding anything that matches my criteria but I am not sure why. Any

Hello, While looking for info on 2^k experimental design and anova I remember I saw somewhere there was a function to generate all the experiments. I can't find the function anymore can anyone suggest? The function takes as input the factors and levels and generates all the experiments. I know I can do it myself using recursion but I want to avoid 1) reinventing the wheel and 2) making

Hi, I was reading the book on "Mixed Effects Models and Extensions in Ecology with R" by Zuur et al. In Section 6.2, an example is discussed where a gamm-model is fitted, with a smoother for time, which differs for each value of ID (4 different bird species). In earlier versions of R, the following code was used BM2<-gamm(Birds~Rain+ID+
