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.

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?

Hi, I've got a problem to use the SJava package with R. I have a SUN solaris 8 machine. Then I did R INSTALL -c SJava_0.65-0.tar.gz without problem Now I try the test provided on the web site: library(SJava) and here I receive the error message: Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library

Hi all, I'm using knn() to estimate the missing values of a matrix and I just want to output the complete matrix resulting from this command. For example m is a matrix with missing values m1<-knn(m,k=10) I want m1 to be a matrix I can work with, that is to say I want to apply mean(m), var(m)...but the format is changed. How do I solve this problem? thanks

Hello R group, I'm using the tseries package to forecast variance and I would like to do the same with correlation. I can't find any way to do that with the function garch(). for example, I have a matrix of time series Date CACIndex SPXIndex DAXIndex NKYIndex 1 05/01/1998 3072.84 977.07 4384.81 14896.1 2 06/01/1998 3037.73 966.58 4352.63 14896.40 3

Hi, Does anyone know how to pass dynamic sql statement to RODBC function "odbcQuery()" or "sqlQuery()"? eg.: under R session, I did: >library(RODBC) >channel<-odbcConnect(...) >data1<-2.5 >data2<-5.0 I want to construct the INSERT sql statement using variables "data1" and "data2" and pass this statement to odbcQuery() . Can I do this?

Hi, Does anyone know how to call stored procedure from RODBC? Thanks.

Dear R user group, I'm looking for a robust mesure of correlation in R. I found a very interesting article by Dr Rich Herrington on http://www.unt.edu/benchmarks/archives/2001/december01/rss.htm and I'd like to implement exaclty this method but my problem is that everything is here developped in R language and is very slow when the correlation matrix is important. I'm wondering if

Hi, I had problem during SJava and ROracle installation. I use "R CMD INSTALL -c SJava_0.65-0.tar.gz" command to install SJava pakage. After installation, I start R session and type library(SJava), error happened as: > library(SJava) Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library
