Let me get more specific. I think it this can be answered then I can translate the information to other calls. In the arima 'R' code there is a reference to .Call(R_TSconv, a, b) If from the console I type: > .Call(R_TSConv, c(1,-1), c(1,-1)) I get: Error: object "R_TSConv" not found If I do > getNativeSymbolInfo("R_TSConv") I get: Error in

Dear members of the list, I'm a beginner in R and I'm having some trouble with: "Error in optim(init[mask], armafn, method = "BFGS", hessian = TRUE, control = optim.control, : non-finite finite-difference value [8]" when running "arima". I've seen that some people have come accross the same problem:

Hi all! Well, I`m trying using a Windows mail client in Linux, called Becky (very good).

Estimados usurios-R: Tengo una lista de alumnos. Hay alguna forma de sacar una tabla de frecuencias por la asistencia a clases mensual. Es decir cuantos días concurrió cada alumno en el mes. Supongamos que la lista está conformada por ocho alumnos, el curso duró 4 días y quiero saber cuantos días concurrió cada uno al curso poniendolo en la columna mes. Quisiera obtener un cuadro así: Alumnos

Hi, I've fitted a GARCH(1,1) for the residuals of my time serie (X). X is an ARMA(1,1) process. Now I want to do a n-step forecast for X, knowing these processes. How can I do this? I know that there's a command: predict() for ARIMA processes and so on, but what about GARCH? I've got: arma=arima(x, order=c(1,0,1)) (...) garch11<-garch(residuals(x),order = c(1, 1))

Hola a todos. Me encuentro realizando un gráfico en R y en los ejes quisiera que los valores aparezcan con separador de miles. Es decir... 1000000 1,000,000 Gracias... -- Paula Altamar Estratificación-DIG-DANE Cel: 3005137541 [[alternative HTML version deleted]]

Hi! I had a database with some variables in sequence. Let me say: TX01, TX02, TX03 and TX04. But I need to run some regressions changing the variables... so: variable <- paste("TX0", 1:4, sep="") for(i in 1:4){ test[i] <- lm(variable[i] ~ INCOME, data=database) } But doesn't work... lm tries to find a variable inside database named variable[i] ... Suggestions?

Hi all, please excuse- I'm a complete newbie to R, so it's possible my question was asked a thousand times before, but I don't get it :-( I imported a CSV file via: x=read.csv("test.csv",header=TRUE,sep="\t") In a column there are values with the dot-character (".") I want to replace with a commata: > x[9] ?????????????????? V16 1???????? GPS

Hello, I?m new at programming and I will greatly appreciate if you can help me with this. I have a very large matrix (hundreds of rows and columns), with the first raw filled with different numbers (between 0 and 1). The rest of the matrix is filled with values 0, 1, 2. What I need is to replace the values in the matrix (except the first row will has to remain intact). In each column I have to

Is terir any known problem with this? Can someone let me know if they are movingp and Solrais with rsync.

HI there I am running this model in negative binomial regression, using glm. I had no problems with running the model with a set of data, but now that i'm trying to run if for new one. I always have this same error when running the regression: > > #Run Regression > x=cbind(factor2ind(d$year),factor2ind(d$month_week)) > > out<- glm(cbind(influenza, n_sample) ~ x,

Great news! Theora is running on FPGA. After almost a year of a great effort we have Theora validated on FPGA. Now I will try to integrated the hardware with a video controller to see the video! I completely implemented the ExpandBlock, CopyRecon, LoopFilter and UpdateUMVBorder functions. The ReconRefFrames function was partially implemented and the part before will run on a software compiled

Dear Paula, There are probably missing observations in your data set. Read the na.action part of the glm help file. na.exclude is most likely what you are looking for. Best regards, ir.

Thanks a lot to everybody that helped me out with this. Conclusions: (1) In order to edit arima in R: >fix(arima) or alternatively: >arima<-edit(arima) (2) This is not contained in the "Introduction to R" manual. (3) A "productive" fix of arima is attached (arma coefficients printed out and error catched so that it doesn't halt parent loops to search for

Hi Paula, This error is fine. The buildbot has tested the worker version. 0.8.x apparently does not have that method. The error gets handled gracefully on the server side. At least it seems so so far. That should not prevent your bot from connecting.

Hello. I have a hudge problem, don't know how to deal with it... I'm supposed to implement a tree structure in R, without using rpart library... I don't have any clue about appropriate approach... Anyway, I can't use pointers under R...so how to to it? lists, vectors... Anyway, does anybody knows how the regression tree in rpart was implemented... Someone please help! Thanks, ana
