Hello R group Do you know if an EM algorithm exits for R to estimate missing data in a sample? I just found knn algorithm in to the package emv but it doesn't look to be the usual EM algorithm.

Excuse me. I don't understant how to use the function "stack". I'm not sure to know the good syntax. I've got a data witch column names are the time when the mesures was done and an other who indicates the age of the subjetcs. I would like to do a new matrix with patients older than a value and the new matrix will contain in the first column the time of the mesures and in

Hi. Samba 1.9.15p8 under IRIX 6.1 (yes I know, it's old stuff ...) The susers on Windows 9x/WindowsNT just put their strange file name or directory name (like /usr/people/mesure_?t? ) on the IRIX. However, from the IRIX side, it's impossible toaccess to such files/directory. What's more, my ARkeia backup client stalls on such a name and fouled up my backup database... NB: Oops: for

could someone help me to write a fonction doing an exponential smoothing in case of a multivariate time serie? I tried ewma <- function (x, lambda = 1, init = 0) { if (is.ts(x)) filter(lambda*x, filter=1-lambda, method="recursive", init=init) else stop(message="first argument should be a time serie") } but I can't apply that to multivariate Thanks

Hello, I've got a problem using the function "running" in package gregmisc For example: test<-c(1,2,3,4,5) running(test,fun=var,width=3) gives 1:1 1:2 1:3 2:4 3:5 NA NA 2 3 4 which is wrong because var(test[1:3]) [1] 1 Where am I wrong?

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 Yaya You will get more responses if you can post in English which is the language of the list. If you want advice about package choice you need to tell us what packages you have considered and rejected. You would also benefit from searching the CRAN Task Views - possibly the Psychometrics one might help you. If you want someone to send you code, as appears from your mail, you are out

Dear useRs We have a data-set (comma delimited) with 12Millions of rows, and 5 columns (in fact many more, but we need only 4 of them): id, factor 'a' (5 levels), factor 'b' (15 levels), date-stamp, numeric measurement. We run R on suse-linux 9.1 with 2GB RAM, (and a 3.5GB swap file). on average we have 30 obs. per id. We want to aggregate (eg. sum of the measuresments under
