hi, in 1.9.1, the return value from ARMAacf(pacf=TRUE) is not named by lags, contrary to ?ARMAacf. the simple fix is to move names(Acf) <- down after if(pacf), with an appropriate starting lag as pacf=TRUE appears to start at lag 1 (whereas pacf=FALSE starts at lag 0). for consistency, one could argue to append 1 for lag 0 for pacf=TRUE (or start pacf=F at lag 1). however, given the

Dear all, I need to compute the ACF (autocorrel) of an AR6 process, given the values of its parameters (w1,w2,w3,w4,w5,w6). First, I notice that there is an error as soon as the sum of the wi equals 1 : "Error in drop(.Call("La_dgesv", a, as.matrix(b), tol, PACKAGE = "base")) : system is computationally singular: reciprocal condition number = 1.00757e-18"

('binary' encoding is not supported, stored as-is) Hello, I don't know if you knew that there's a russian site where you can buy your music in Ogg Vorbis. There are many albums where you can decide what Codec (MP3, AAC, WMA, Vorbis, MP+) and Bitrate (or quality for Ogg) should be used to encode and download the files encoded specifically for you. The prices are somewhat low.

Hello I would like to generate covariance matrix with autoregressive structure. I saw some functions in nlme such as corAR1 for example but I don't know how to use it for my goal. Could someone help me or advise me another function? Thank you in advance Caroline

To whom it may concern, I am interested in generating data from an ARMA(p,q) process in R. I know that there are functions in S which allow for this, but I don't know if such functions exist in R. Do they? And if so, what are those functions? Thanks, Carsten Botts e-mail: cbotts at stat.ufl.edu -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help

Hello, I am working on extracting data from sound recording (fee bee song of the black-capped chickadee). I obtained a two column matrix with x=time(s) and y=frequency(khz). The part of the recording that is interesting me is when the frequency is stable. Does somebody ever used a fonction that extract only constant data among a huge list of data (sample= 180000)? Thanks Thibault Grava

Hi, I tried to use S-plus script with R. I thought it was easy because there aren't a lot differences between S-plus and R syntaxe. However, I didn't succeed to use stepwise function in R. I think the best equivalent in R is step, but this function seems not to use same parameters. is there a better equivalent in R ? or package to make stepwise compatible with R ? Thank you for

Hia .... i try to use the fonction Getvar of asterisk to get a variable myDNIS that i have define. i use it as follow Action: Getvar Channel: SIP... Variable: myDNIS but asterisk don't know it .i have the response as follow Response: Error Message: Invalid/unknown command does everybody meet this problem . i try all possible combination and nothing help please ..!! :-( thanks in advance

Dear R users, I'm performing some GLMMs analysis with a negative binomial link. I already performed such analysis some months ago with the lmer() function but when I tried it today I encountered this problem: Erreur dans famType(glmFit$family) : unknown GLM family: 'Negative Binomial' Does anyone know if the negative binomial family has been removed from this function? I really

I would like to figure out the equations for calculating "AIC" in both "step() function" and "AIC () function". They are different. Then I just type "step" in the R console, and found the "AIC" used in "step() function" is "extractAIC". I went to the R help, and found: "The criterion used is AIC = - 2*log L + k *

I've rolled up R-1.5.1.tgz a short while ago. This is a patch upgrade, fixing the most important bugs that cropped up after the 1.5.0 release. A set of recommended packages which have been tested with R-1.5.1 has been bundled up. Binary distributions should include these packages. You can get the files from the developer site ftp://cvs.r-project.org/pub/CRAN/src/base/R-1.5.1.tgz

I've rolled up R-1.8.0.tgz a short while ago. This is a new version with major changes (see below). Notably, the Macintosh version for OS X has been substantially improved; the old Carbon interface is no longer being supported. Also notice that the underscore will no longer work as an assignment operator. There is also a bunch of new functions and an assortment of bugs have been fixed. You
