Hello, I would like to sample a population but the result needs to be reproducible, using 'runif' or 'sample' is the good way to do it but I can't manage to make the results reproducible even with the 'set.seed' function. My aim is that th call to 'sample(1:100,10)' gives always the same result, how can I do that? Thanks! Eric Esposito

Dear all, I'm looking for how can I estimate a linear model with ar(ma) errors : y(t)=a*X(t)+e(t) with P(B)e(t)=Q(B)u(t) where u is a white noise and P, Q are some polynomes. Could you help me ? Gr?gory Benmenzer

After reading the readme.packages file, I would like to install the R tools in order to build my own packages, but the internet portal http://www.stats.ox.ac.uk/pub/Rtools/ hasn't been working since a few days. Where can I get the file tools.zip? Thank you! Eric Esposito

I'd like to know if there is a way in the proc arima of the ts package to calculate the p-values of the parameters estimates if it used with the xreg option. Thank you for your answer. Regards, Marion Cordi?

Hello, We are using the new version 1.7.1 of R with the R-(D)COM Interface 1.2 through Excel. But we failed using the ARIMA and SUMMARY functions: the Statconnector doesn't work even if these functions work under R. Please, could you explain us how to solve this problem? Thanks a lot! Marion and Jeanne

Hello, Does anybody know if the function arima with an external regressor (xreg) applies the auto correlation on the dependant variable or on the residuals. In comparison with SAS (proc autoreg), it seems that the auto correlation applies on the residuals but i'd like to have the confirmation. I want to estimate: Y[t] = a[1]*X[t] + a[2] + E[t] with E[t]=b[1]*E[t-1] Should I use : arima(Y,

Hello, I need to execute R code contained in a file xxx.R from DOS. The file is really simple, only: > plot(rnorm(100)) When I launch Rterm from Dos command and then source the file xxx.R it works, but I need to call the command from a DOS command file *.bat Using Rterm --slave < xxx.R plots the graph in a postscript file Rplots.ps, how can I do to get the graph in an R window. Using a

Hello, I am a beginner user of R and I would like to estimate a model with AR errors. I use arima function: modele <-arima(conso,xreg=var.exogenes,order=c(ordre,0,0),include.mean=TRUE,method ="CSS") My inputs are dummies for each month except one, and the same thing for each day and each hour. I have this error message: Warning message: possible convergence problem: optim gave

Hello, I'm trying to insert a vignette as a word document in my package. After compiling and installing the package, the word file is in the doc directory, but no link in the html index for vignettes is created. I tried with a pdf file and there is the same problem. It seems that only sweave format files are taken into account, is it normal? Is there something special to do to take other file
