Dear R-list, i have a problem, in the framework of simulations, i want to vectorize for earning time: a variable, say X, has values on intervals and an other variable, say Y, has values on other intervals. For example Inf Sup X 0 2 1 2 4 2 4 6 3 and Inf Sup Y 1 3 1 3 5 2 5 7 3 i want to create a matrix like this Inf Sup

R-users, i have some time series and use HEGY seasonal UR tests in the uroot package. But i have problems with interpretation of t and F statistics. Is there any critical values for these tests in R? is anybody ever write a bootstrap of these tests? thanks for advance, with all my bests, erik. ================================= Erik-André SAULEAU SEAIM Centre Hospitalier 87, Avenue

Dear R-list, I try to use StructTS for some univariate time series, with a type="BSM". I have two questions: 1-in the "fitted" value of the object, it seems to me that for getting back fitted values, one have to add level, slope and seasonal (or "level" contains already the two other ones) 2-i am really circumspect about the results of "KalmanForecast"

Hi I am still having problems with using the stl function, when I read the csv file into R into a file called tkr and use dim(tkr) the result is 132 1 which is fine. When coerce it into a trime series using ts either: tstkr <- ts(t(tkr), deltat=1/12) or tstkr <- ts(c(tkr), deltat=1/12) and use the stl function I get the following error: Error in

Dear R-list, I try to adjust GLMM on incidence cancer data. Without random effect, in GLM the command is, for example with sex effect, glm(Observed~sex+offset(log(Expected)),family=poisson) because the observed are Poisson distribued with parameter Expected*incidence rate. But know I want to introduce random effect (for example spatial effect) and it seems to me that the "offset" does

Dear all, I want to use GraspeR (on R 1.6.0) and have to install tcltk library. When I try to do this, I get back this error message: Error in firstlib(which.lib.loc, package) : TCL_LIBRARY is not set Error in library(pkg, character.only = TRUE) : .First.lib failed But I have a tcl/tk package (Active TCL 8.4.1.0) correctly install on my PC (Win95) and in the autoexec.bat the

Dear R-list, I wish a very happy new year and send you a little question: I have different variables which names are m1, m2, m4, .., m10, ... and want to obtain for example mean of each of them without typing each mean(m1), mean(m2), .... What is the solution for decomposing names in mXX? With my best regards, EA. ============================================ Erik-André SAULEAU SEAIM Hôpital du

Hello R-List I use DClusters package (I work in a cancer regestry). I have 2 questions about it: 1-how is it possible to get back the bootstrap pValue? I mean the pValue of the calculated statistic with respect of the distribution of this statistic under the null hypothesis. 2-how is it possible to test an overdispersion in the poisson model? for choosing a best model I need this mesure of

Dear R-list, I think it's really a newbie question but ... I try to model age-period-cohort models with polynoms in each effect. I have for each level of age and period some cases -k- and persons-years -py-. Models are A_xP_y: log(k_age,period/py_age,period)=f(polynom(x),age)+f(polynom(y),period). For exemple I try to adjust an A2P3 :

Dear R-listers, I have to explain "y", a continous variable, with two variables "t" and "p" which are "factor variables": t is [1:12] and p is [1:18] (a value for y for each combination t*p). OK, then I try to adjust models like: y=a_p + b*t (I mean as many intercepts as levels of p) or y=a_p + b_p*t (as many intercepts and coefficients for t as levels of

Of course Sven, questions regarding LLVM belong here (clang questions should be directed to cfe-dev). Developers on this list are usually very helpful when it comes to answering questions that are clearly stated and show that the person asking has done a reasonable amount of investigation and is just stuck. It usually helps to start with a succinct description of what it is you are trying to

Hi, Before I reinvent the wheel I wanted to kindly ask you for your opinion if there is a simple way to do it. I want to merge a larger number of tables from different data sources in R and the matching criterium are country names. The tables are of different size and sometimes the country names do differ slightly. Has anyone done this or any recommendation on what commands I

Hi, I'm new here and I would like to know what's the best place to ask for some structural questions or help? If that's the right place, I'll send another email with the details and my question. Thanks in advance! Sven -- Sven SAULEAU +33 6 28 69 51 44

Hello everybody, I want to use the nnet library and my problem is that the algorithm seems to accept only class as target when the neural is fiiting. So the output when I use predict.nnet is also a class. Is it possible to have numeric variable as target ? If yes, what is the syntax ? Thank you. Cordialement, R?gis CHARIGNON

Hello, I am almost new in R, so perhaps my question will be silly. I try to use R for analyzing capture-recapture data in epidemiology. A cancer registry has different sources of patients. We know in each list, patients already known in all other list. The aim is to use capture-recapture models for estimating the number of patients unknow of all the sources. Because no order in sources, one

Dear helpers I'm having a problem with function HoltWinters from package ts. I have a time series that I want to fit an Holt-Winters model and make predictions for the next values. I've already built an object of class ts to serve as input to HoltWinters. But then I get an error; I've used HoltWinters a lot of times and this never hapened > data.HW<-HoltWinters(data.ts) Error

Dear list members I want to analyze separately the months of a time series. In other words, I want to plot and fit models for each month separately. Taking the example of http://a-little-book-of-r-for-time-series.readthedocs.org/en/latest/src/timeseries.html births <- scan("http://robjhyndman.com/tsdldata/data/nybirths.dat") birthstimeseries <- ts(births, frequency=12,

Hi everyone, I'm using the HoltWinters() function to do a time series analysis. The function only returns the back fitted values ($fitted) after the first year of data, which is my case, is a little more than half. However, when I use the plot() function, it plots the back fit for almost the entire data set. Any ideas on how to extract the fitted values going all the way back to the start

Hi R-users, I have a question relating to the HoltWinters() function. I am trying to forecast a series using the Holt Winters methodology but I am getting some unusual results. I had previously been using R for Windows version 2.7.2 and have just started using R 2.9.1. While using version 2.7.2 I was getting reasonable results however upon changing versions I found I started to see unusual
